Thomas, Ryan, Crash and the gang join Mater, Lightning McQueen and their friends old and new in a brand new round-the-world adventure.
Prologue: The message from Leland Turbo
The film kicks off with a red car named Leland Turbo sending a message to Finn McMissile. He says that he found something and that his cover has been compromised. Then as the door opens, he cuts off the transmission. The opening titles play.
Finn on the rig/Faking death
Later, that night, a boat named Crabby is floating along the water with Finn. He says they have arrived, and asks why they're there. Finn tells him he's looking for a car. Crabby tells him that they're the only ones out there, but a war ship shows up and tells him to turn around. Crabby tells Finn that it looks like it's just the two of them but Finn has gone. Finn has snuck up on the ship and is climbing an oil rig. However, there are multiple oil rigs. When the Lemons pull out a camera, two more Lemons, the ones from the message, bring out a box. It turns out to be Leland Turbo, who has been crushed and cubed into scrap metal. Shocked, Finn doesn't notice fire come out and reveal his shadow. Professor. Z looks up and sees him. A chase begins, and Finn jumps off the rig. He gets away and fakes his death by sending four fake tires up to the surface. Professor Z muses over how no one can stop him now.
Radiator Springs/the challenge
In Radiator Springs, the Cyberlings cheers for Mater as he pulls a lemon in for repairs. Mater tells them about he is excited for Lightning McQueen's return. He then sees his best friend crowded by his friends and our heroes. Archangel and Psylock are there too. Evil Ryan looks at the camera and said "I guess Disney owns Marvel and Pixar." Deadpool places a bag over his head and tells the audience to not listen to him. Evil Ryan said what he mean to say that Deadpool is so happy for McQueen's returned, but Deadpool throws him into the tire shop, saying that's not true. Psylock rolls her eyes. Evil Ryan climbs onto Mater and saw that the Radiator Springs gang and our heroes are by Lightning. They go to the abandoned tracks, roll down them, and run from a miner train. Afterwards, Evil Ryan and Deadpool do some tractor tipping, but on a huge truck. Evil Ryan sighs and ask Deadpool "At least things like this cannot get any worse.". Then a blast of air sends the two flying and land on McQueen and Mater. Later, at sunset, Ryan and Twilight look at Crash and Sunset (who are in the forms of Daydream Shimmer and Daydream Crash) watching McQueen and Mater coming back from their big hang out with the others. Ryan tells Twilight that he's so happy that McQueen and Mater's friendship has never died. Matau ask Ryan how did Sci-Ryan gain his trust in Gaia and Ryan says it's because he's the one who trusts her the most and knew what she was doing was right. Crash ask what was Gaia doing to do at Camp Everfree, then Flash Fire crash lands, saying he was trying to find his way to Starling City to check out the El Pablo's restaurant. Daydream Crash ask Flash where did he come from and Flash admits he has been taking way too many wrong turns, he doesn't remember. Deadpool then tells Flash that when he gets there, say hi to Hawkeye for him. Emma Frost and Psylocke annoyingly remind him his name is Green Arrow. Ryan shows Deadpool two photos: one has Hawkeye and the other Green Arrow. Meanwhile, Mater and McQueen talk about their plans for the evening. Deadpool then says that the purple one is an imposter. Suddenly a portal opens. Ryan informs Deadpool that Twilight is his friend. Then Penn Zero, Sashi, Gloriosa Daisy, Boone, Timber Spruce and Oswald the Lucky Rabbit come out of the portal. Ryan hugs Gloriosa and pulls out two jewels: one red and one purple. Oswald ask Ryan what is he going to do and Ryan said "I'm giving Gloriosa the power she needs to become Gaia Everfree.". Deadpool ask Sci-Ryan "Who is Gaia Everfree?" Nighlock grabs him, telling him that the president wants to see Code Red. Deadpool packs all his weapons, even Root Bear Launcher. The other watch as Gloriosa transform into Gaia Everfree, while Deadpool does a cliffhanger in the scene, saying they need to get to the next scene.
At the Wheel-Well Motel/Thomas' suspicions of Miles Axelrod
Ryan and Twilight goes to Wheel-Well with Gloriosa (now Gaia Everfree) and the gang where McQueen's girlfriend, Sally, is preparing to close all rooms. She asks them where's Deadpool, Ryan and Gaia told her that Deadpool has a meeting with his friends. Then, as the others have a chat, Ryan asked Gaia what causes her to change into what she is now and Gaia explains the gems were what caused the transformation. Sci-Ryan is amazed by what Gaia said and said "These gems must be the geodes with Equestrian magic but she can control it like Twilight before she became what Ryan did at the Friendship Games.". On the TV, there's a two cars called Miles Axlerod and Francesco Bernoulli. Francesco criticizes McQueen for preferring to be slow and says that he is faster than him. Ryan ask Gaia why did she confront Ryvine and Rothbart and Gaia explains it's because Ryvine was angry for her reformation. The 12th Doctor ask Ryan why he saw Ryalight Glimmer fighting Cody, Ryan and Codylight (a mixture of Twilight's and Cody's names put into one) then Starlight said: "I think it is because it's Ryan from another dimension is doing what I did.". Ryan asks Flash Fire how he got lost in the first place. Flash says he got directions from Flash in Zootopia, but he may have gotten the wrong directions. The Cyberlings chuckled at that and Evil Ryan said he's happy that Ryan is with Twilight again but Ryan reminds him that this is before Twilight merges with Primus. Crash ask Ryan who did Nurse Nancy Cortex transform along with Ryvine, Gloriosa and Ryan and he said "Well, Gloriosa wants Ryvine's help so she gets empowered by the magic of the geodes and became Gaia Everfree while Ryvine, Nancy and I turn into Everfree Prince Gale, Gavine Sparkle and Nanc-anos.". Meanwhile, Mater chats to Francesco over the phone to Ryan ask Thomas why is he looking at Axlerod and Thomas tells him that there's something not normal about that car. Crash ask if he's not normal by his paint or Ryan diving into Primus but Thomas explains Axelrod is not normal because of the way he is designed. Ryan figured out that both Twilight and Ryan are royalty and Miles is releasing a new type of bio-fuel called Allinol and it works real well. Sci-Ryan agrees and tells Gaia to turn Ryan into Everfree Prince Gale so they can sing "We Will Stand For Everfree", she does then she and Ryan (now Everfree Prince Gale) sing the song with Sci-Ryan watching them.
Code Red with the president of the US and Senator Kelly/suspicions about Allinol
In the White House, Crash Bandicoot, the Cyberlings and the Code Red team talk to the Senator of New York, Robert Kelly while waiting for the president and the Secret Code Red. Red Smoke teases Nighlock about his girlfriend(who happens to be Shadowcat), but Nighlock cosmically zips her lips. The Cyberlings then ask who is girlfriend is, but Crash tells them to keep quiet. The Secret Code Red walks in. The president follows in behind, and sits at the front of the room, facing them. He then tells them that some of the CIA agents managed to get a sample of Allinol, and have discovered that it can be flamed with an electromagnetic pulse ray. Evil Ryan told the president that they need a team that can reverse the effects and Bertram hinted by saying "2 words. Worst. Heroes. Ever." Nighlock corrects him, saying that that is three words. Crossbones comes in with smoothies, saying he ruined the moment. Senator Kelly tells them that someone may have tampered with it, but Nighlock admits his suspicions that that may not be the case. Bertram gasps and saying the race is run by Allinol and the EMP rays could make the engines of the cars to blow up and kill them. Shadowcat uses her smarts and says that depends on what level the EMP Rays are on. Evil Ryan ask Nighlock if he have a sister or any other family members, but he tells him that information is classified. After learning about the mission, Code Red packs up their things and heads to Tokyo.
Crash signs McQueen up/Getting ready to leave
Meanwhile, Crash is signing Lightning up for the race. Magneto is buying tickets for a plane ride to Tokyo, while Storm makes sure no unexpected weather knocks the plane out of the sky. Ryan (as Everfree Prince Gale) is fetching some passports, while Nur teahes Starlight and Gloriosa Japanese. Evil Ryan tells Gloriosa that though when this idea goes well calling her "Gaia Everfree", which makes her more than happy to tell her brother to come with them. Evil Ryan asks Agalope (who is the leader of the Dark Stars and Evil Ryan's girlfriend) why is he in the race and Agalope told him that McQueen can prove everyone what he can do and win every race. Jessie F-Fiona shows up pulls out her geodes and turn into Rivine Everfree. Princess Ivy suggests that McQueen needs a new look for the race but Ramone assures her: "I got this!". Ramone and Ivy give him headlights as well a new coat of paint. Soon enough, McQueen is revved up and ready to roll. The gang is soon getting ready to leave. Ryan told Twilight that he's a Prime and Twilight's a princess. Then Lord Voldemort shows up, and begs them for help recapturing an old enemy of his. Starlight asks who it is, and he replies that his name MetalBasiliskmon... and works for the four Dark Master Digimon. Evil Ryan told Voldemort that he and Harry Potter along with his friends will face them calling him "He who must not be named". Then Nur reveals he only knows of MetalBasiliskmon by his powers. but that last time when he was locked away, he only gave the world a taste of his powers. Maybe next time he strikes... he will give the world the full meal. The others contemplate at this. They then set off for Tokyo.
Going to Tokyo/Sci-Ryan's and Gaia's sightseeing
While All I want is you plays in the background, we see Ryan and the gang get on an airplane with McQueen and some of the others. Crash read "How to find Yo-kai" while the others watch a Japanese version of the American TV show, Wipe Out. Rigby (EG) and his sister (Princess Odette) fall asleep, but Odette has nightmare/vision of the Dark Masters. Crash wakes her up, and asks her what she saw. She says she saw a giant sea serpent made of metal, a mechanical dragon, a puppet that looked like an evil version of Pinocchio, a clown from Hades, and a basilisk made of metal. As Odette calms down, Rigby (EG) sense that Rothbart might be with them but the others don't notice this because they are now arriving in Tokyo and Ryan summons Robonyan by using his Yo-kai watch to teach Gaia and Timber that the true meaning of friendship can solve any problem. One of the Starrings, Scar (EG) talks to a car who is a prophet on vacation, and he tells them that they are the creatures in Odette's dream were the 5 Dark Masters, the unholy and most evil of all Mega level Digimon. The gang learns from Nate that they were feared by all. The prophet tells them that they have not been active for more than 3 years. He warns that Odette's vision means that they must be up to something for her to have a vision of them. Sci-Ryan said the robo-snake is no better than Morro and the Daleks. The prophet warns that while MetalBasiliskmon may not be any better than the ghost or the aliens, but he's worse. He tells them that in order for a Basiliskmon to digivolve into Mega, they have take the remains of any Digimon equipped with Chrome Digizoid metal. Thomas thanks him for letting them know and Evil Ryan tells Sci-Ryan and Gaia to have some sightseeing, also noticing Deadpool wearing a moustache. "You can't say my name here, this is one of the countries I'm wanted in," he tells them. As if to confirm it, the police arrive and chase Deadpool around. The gang split in groups, Ryan and the Dazzlings with Megatron and Twilight takes them to the shop. Meanwhile, McQueen chats with some of his old friends at the pre-party and Ryan is so happy Twilight is still ok after she's revived. Whilst they are talking, Crash notices black and white butterflies which belongs to Princess Ivy (who is looking scared). He asks her what is wrong, and she tells him that she cannot hear Sofia's voice, and cannot contact her. She says she fears something happened to the kingdom. The camera then switches to show the audience they are being secretly watched by a telescope while evil laughter is heard.
Sci-Ryan meets Nate Adams/Thomas and Ashima reunited
Sci-Ryan and Gaia Everfree (who is Gloriosa Daisy) are still sightseeing when they bump into Nate Adams (quite literally). Sci-Ryan notices his glasses are not on his face and Gaia finds them and puts them back on his nose. Nate apologizes and notices Sci-Ryan has a Yo-kai Watch on his wrist which looks like Nate's but it's purple. Sci-Ryan looks at the watch and two Yo-kai called Whisper and Jibanyan who tell him they too are friends. The two hug and Sci-Ryan said he's so happy to see that someone else has a watch. Meanwhile, as Ryan has a chat with Twilight, they are watched closely by a Serpentmon, one of MetalBasiliskmon's servants. They don't seem to notice, as it is disguised as a normal human. Whilst this is happening, Thomas spies Ashima, an old friend of his, and goes over to her. Ashima comes to Thomas and hugs him, making Twilight a little jealous. Ryan tells Twilight to calm down and say that she's a friend. Twilight agrees and said "That is some nice advice, Ryan. The Prime-prince of Friendship.". Evil Ryan told Ashima the story of how he and Merlina turn into Dark King and Dark Queen, and Ashima tells him to not let the darkness get the better of them. Nate asks why she says that, and she says darkness has a way of slithering around unnoticed (it is possible she aware of Serpentmon's presence). These words cause Serpentmon to retreat, fearing he has been discovered.
Miles Axelrod's speech/Mater in the bathroom/Mater meets Holly
Later, Megatron asks Evil Ryan why did he turn into Dark King then Evil Ryan said "You know why.". Nate asks Evil Ryan what did he do in Ryan and the Black Knight, Deadpool accidentally gets himself and Ryan arrested. Evil Ryan tells the police to release Ryan as he hasn't committed a crime. Nighlock tells them to release or he will personally throw the cops in jail. The cops let him go. Ryan thanks Nighlock and calls him a buddy and them. Evil Ryan saw a vision of himself and Merlina transform into the Dark Queen and the Dark King but Ryan snaps Evil Ryan out of it and then Evil Ryan saw Merlina (the Dark Queen) come over with tea. The Doctor asks Evil Ryan if he knows her and Evil Ryan said "We met in Ryan and the Black Knight.". They don't realize that they are being tracked by Machinedramon, who is tracking them using the energy source of the TARDIS. The gang then watch as Miles Axelrod gives the crowd his speech. The gang then watches as Mater rolls up yelling in pain and drinking the water. Mater then tells the crowd to not eat the free pistachio ice cream (wasabi). Red Smoke rolls her eyes and tries to silence him. Miles Axelrod says it is alright. But then he notices Mater leaking oil, embarrassing Lightning. Deadpool, who is wearing black and white prison stripes after escaping, follows him. Meanwhile, Finn is revealed to be alive. Ryan looks at Mater and follows him but he gone to the girls bathroom by mistake. He then goes into the boy's bathroom. Finn meets up with Holly, and the two see Professor Z, his goons, and Kiwimon (signifying Professor Z is in business with the Dark Masters). The two agents agree that Holly will meet the American agent who was on the Rig as well. Meanwhile, Mater finds an open stall and is in awe at the fancy tech. He presses a button, but finds the wash a little overbearing, not even noticing the Lemon that comes in and reveals he is the American spy. As the American car checks out his reflection in a mirror, Ryan sneaks in and hides from the sight of two Lemons, who come in and ambush the American spy. Ryan gasps, but Deadpool covers his mouth and reminds him not to ruin the plot, while also commenting that it is pretty scary that he's reminding people not to ruin the plot. Mater is still having trouble with the wash, but the two Lemons have the upper hand against the spy, until Mater finally comes out of the stall he was in, ending the fight. Ryan asked Mater if he's ok, and Mater tells everyone present to not go into the stall he was just in, no one noticing the spy placing his information onto Mater. Mater turns around and sees the injured spy. The spy tells Mater and Ryan that he's alright, and the Lemons tell them to get out of there. Just as Holly is about to go into the boy's bathroom, Mater sees her. She uses the code to know he is the agent. Surprisingly, he gets the answer right. Ryan is confused and looks underneath Mater to find the device. Before he can inform Mater however Sidecord and Spikewave (who have been looking for them), come and take them back to the others.
The Lemons kill the American Spy/the First Race/McQueen loses the race
Meanwhile, at a warehouse, the Lemons cuff the American spy down and feul him up with Allinol. He comments how he has heard that is good for you, but a RedVegiemon says that's what everyone should think. As the spy wonders what the Lemons are doing with the Dark Masters, Professor Z rides an elevator and explains what happens when Allinol is hit with an electro magnetic pulse ray. The Lemons show him photos of the American Spy disguised as a Lemon talking to different cars as they charge up the camera from the rig, which is an electromagnetic pulse cannon in disguise. When shown the photo of Mater and the gang in the bathroom, the American spy doesn't say anything. Professor Z realizes he gave the information to them and contacts his boss. He tells the other Lemons Mater and the gang must be eliminated, something the Dark Masters take great fondness of. The camera shows the Lemons fire the cannon off screen and kill the American spy as the camera shows the picture of Mater and the gang while fire glares the picture. At the race, Lightning is fueled up and enters the starting line. Just as he closes his eyes and says his catch phrase, Francesco mimics him. Lightning says he is so getting beat today. Meanwhile, Finn, Holley, and Slade are watching the race in a building that overlooks the race. As the first lap of the race ends, the Lemons fire the cannon so the Allinol flames up, but doesn't kill the racers. Which causes Bertram and Malfunction some suspicion and makes Holley, Slade, and Finn spring into action. After hitting another racer, Grem and Acer spot Mater and the gang in the pits. Acer goes after him and so do many other Lemons in the audience watching the race. However, it catches Finn, Slade, and Holley's attention and learn they are closing in on Mater and the gang. Finn and Slade race to distract the Lemons. Ryan and the Dazzlings help Finn and Slade fight the Lemons while Mater and the rest of the gang watch, Mater thinking it is a karate demonstration. Galvatron (after changing from his TP Megatron form), arrives to help. Finn takes out all the Lemons, and Mater congratulates him but Finn is gone. Crash wonders who the car they just saw was. The race continues but ends with McQueen losing to Francesco.
Mater returns to the pits/Lightning's anger outburst
Sometime later, Mater comes back. Lightning asks what Mater was doing and Mater explains what happened but soon realizes what he made Lightning do. Lightning shouts at Mater, saying he lost the race because of him. Mater tries to apologize but McQueen's anger prevents him from the accepting the apology. Thomas and the others try to calm Lightning down but
