One day, Snowdrop and Primrose were hanging out on a spot where Primrose and her mother use to be at. But tomorrow, it is shown that Primrose was no where to be seen. Just a message in a bottle no one can read, however when Gobber read it. He explained that Primrose has gone to "Doom"! So the foals, their dragons, and all their friends go on an incredible journey to find her. But however on their journey, they are hunted by a mysterious predator. And worst of all they are being chased by the Cloggersaurus.
The beginning of the story
The story starts out with Snowdrop narrating the story, beginning with her life and how everything went. And then she explains how they discovered Berk and made friends with the dragons. And then explained about her mother and then adds that their real adventure is about to begin. Then after the title appears, the dragons were playing hide and seek with Snowdrop. And Eaglesight pounces on her and begins licking her. Then hears Primrose, she then comes to a cliff on view. And then she tells her daughter that she and her mother come here all the time when she was a foal. But she was unable to tell Snowdrop some bad news, and she begins to fade. But tells her some advice, "You're braver than you believe, and stronger than you seem, and smarter than you think," and she fades. As Snowdrop is comforted by her dragons, but unknown to her, she and her dragons are being watched by body heat.
The mysterious message/The Adventure begins
The next morning, Frostlord finds a message in a bottle. So then they encounter Skyla, who couldn't take her eyes off of something. When they ask, Skyla says that she sees skinned people. They then take a closer look and see more of them! And then Crystal Heart finds some dogtags, of some soldiers. Snowdrop, Skyla and their dragons then go to find Yuna and Hiccup. When they do, they were surprised. Then Snowdrop shows the bottle with the message. After Astrid opens it, unable to read it, (due to it being covered in mud and party watered out) they took it to Gobber. He then takes a look at it. And makes out: "Dear, Snowdrop, I won't be with you tomorrow because" then he stopped. As Snowdrop is looking at the window. Thinking about Primrose, Human Fluttershy tries to cheer her up, but Snowdrop think it's not for the best. Then Gobber finds out where she went. He then starts makes out an "O" and another "O" and then he gasped in horror! He quickly closes all doors and windows. And then lights some candles and then reads out: "She has gone to D-O-O-M Doom"! Which confuses the others, then Gobber explains that Doom is a horrible place. So Snowdrop proposes they go there and find Primrose. So then Gobber starts to make them a map, Sunil then asks if they will encounter, Hyenas, evil Lions, and Tigers. But Gobber warns them they'll mighty encounter the Cloggersaurus (a rare hybrid dinosaur). He then starts singing "Adventure is a Wonderful Thing". And then as they leave, they are being watched by body heat.
The strange noise/Predator encounter
The team are now out in the unknown and then suddenly Skyla sees something! It was a rock. They then herd a strange sound. They then think it could be the Cloggersaurus and they all began to run around in different directions. When Astrid stops them all and takes the map, and they go to a passage. Meanwhile, Skyla is feeling some pokes, then they all heard the growl and she runs out to a valley of flowers. There, she finds a deer nearby, but then something hits it and then the deer is killed! And Skyla sees a invisible figure. She then draws fire at and continues firing like crazy, then everyone else races in and joins in and then they all continue drawing fire and then they all stop. Skyla then states she saw an invisible man, but Nyx denies it. But Zeñorita states that since they don't know what it is, they have to conclude it's an invisible man. Yuna and the spiders then take a look at the deer. Then Gail and Zoe come back after taking a look and have found no trace. Then they heard the growl and then they race off as the man appears takes the deer's skull out.
Lost in the fog/"If it says so"
Later, the group get lost in fog. As Astrid is trying to figure out which way to go, some of the foals think that they should go other ways. But Astrid thinks she knows the way "If It Says So". but then she loses the map! Moon Starlight goes after it, but is over a cliff! And then she ends up stuck on a log down below the cliff and it rips in 2! She then screams for help as the log half lands on a between. The others arrive and make a ladder and grabbed Moon Starlight, but Aranea sees red dots and it blasts them down! They fall down as they landed into a ravine below and then when they get back on their feet the 2 halves of the map float down as Astrid catches it. But they heard the growl and ran off.
Lost again/"Where Ever you are"/Snowdrop's story
The team are now lost in some really thick fog while as Astrid is trying but failing to figure out which way to go. She then believes that she isn't smart enough to figure out which way to go, although Snoutlout disbelieves it. Then Snowdrop convinces they'll sleep for the night, and the others agreed. But Joy is awake and says "What Skyla show was no man, it's waiting for us, and we're all gonna die". Then Fluttershy (human) notices Snowdrop on a cliff, where She is looking into the sky singing "Wherever You Are". Then after the song, she is met by Fluttershy (human), who puts a blanket around her. And she asks about her past was like. Snowdrop explains that she was born blind, and at school the other foals would make fun of her and doubt she could do anything and that was when the CMC befriended her. And then when the dragons attacked, her mother held off a Monstrous Nightmare, and she explains about how she feels lost without her. As Fluttershy (Human) assures her that the Royal Night Family are her new family, and her dragons are like her own brothers. At the same time, the man is watching them.
Then Skyla wakes up and sees something, not the invisible man but something else. She then screams in fear, that wakes up everyone. She then points up and there, right in front of them is Doom! And they wonder if Primrose is inside. Then they hear the growl again so they race inside, but the invisible man watches them. Inside, the team come up to a huge fork in the path and wondered which way to go. Snowdrop then ponders and concludes that they could split up. So each of the team take a different path. As they go down each one they hear sounds, and Nyx heard some even scary strange sounds "Boo, Boo, Choo, Choo". Then hears something coming from the corner. And then, it was the spiders. Then they got blasted, it was the being that was stalking them! Nyx then fires back. But it appears with sharp spears but it gives chase to them, and they come to a dead end. And Nyx tells them they have to jump. The spiders have to agree and they jumped down but are catapulted on a branch that has a face of a Triceratops. Astrid, completely afraid falls down a massive hole! And then tumbles head over heels down a tunnel. Meanwhile in another place, the other riders come to a dark place and encounter bats. And they race away in fear. Then Skyla and Crystal Heart slip on small rocks. And then fall over a cliff and land on the branch the spiders are stuck in and it broke loose. Then Nyx felt a bump and runs for her life. While Snowdrop is alone in a crystal room. Then Astrid pops out from the tunnel and lands in a huge room as her axe follows behind and hits her. Then the others came in and all piled up. Then they all heard the growl and look up and see the Cloggersaurus (which is actually Snowdrop behind the crystals). They then run away and race down a tunnel while Snowdrop walks out from behind the crystals and slides down a slide. The others continue running and then slip, and almost fly over the side of cliff, but Snowdrop continues sliding down a slide and then she gets stuck between some crystals.
The O of Doom
The others manage to get back on level ground and then up above them, Snoutlout sees something, there was the O of doom! Astrid then figures that since the map is useless she should try to come up with a plan from scratch, she decides to give it a go for Snowdrop. And she starts thinking hard and then she gets idea after noticing a huge root hanging from the O, and if Moon Starlight can fly up and bring it down, the others can climb up. Moon Starlight is unsure of it but decides to do it for Snowdrop. And flies up, then she reaches the top and pushes it down. Then after she slides back down it, Snowdrop gets unstuck and then slides down into a slide. Where she then goes to the bottom. She then tries to climb back up but to no avail, then she tries to fly up with little success. (due to her injuring her wing on the fall). She then starts to mourn that she will never get out and when she starts loosing hope, Obi-Wan (in spirit) shows up and he encourages her to carry on to get out. But Snowdrop tells him she doesn't know how, but Obi-Wan instructs her to look withing herself and know what to do and fades away.
Reuniting with parents/Snowdrop vs. the Predator
Back with the others, they have now made it up to the O of Doom, but they herd a foot steps and see shadows approaching, but it turns out to the be the Mane 6, The engines, Brian, the Eeveelutions, Zecora, Green Bills, and the royals! And the foals hug them. And they asked them where they been, as Fishlegs explains that they were searching for Primrose and then Primrose shows up in spirit. Yuna then asks about where she was, and Primrose shares that she was at Desk, which confuses the others. As Snoutlout shows the letter said she was going to Doom. But she says, "Dear Snowdrop I'm not going to be here tomorrow. Because I have a meeting at Desk, I will be back at the after noon. Signed, Primrose". Just then, Astrid remembers that the Cloggersaurus got Snowdrop, in which they all hear the growl as everyone panics and runs around the room, but it shows it was Rexy looking for them too which explains the growling, as Zoe then faints out of surprise. Then Snowdrop is still trying to figure a way out, when she heard Rexy's growl then hits something behind her. It was the being! The said being then starts trying to kill Snowdrop by using sharp tools he has.
Snowdrop fires at it, which was a mistake. Then slowly the being takes his mask off which reveals he was an alien with lots of teeth! And Snowdrop calls him: "You are one ugly alien", which makes him roar in anger. Snowdrop then starts shooting again, but the alien then blocks the bullet and slaps her asside. Then he pulls out a long sphere, which turns into an electro staff. Snowdrop sees this with her Force vision. And she pulls out her very own constructed lightsaber and activates it, with a snow colored blade. And the 2 collide with their power sticks, and the others heard it and hoped on their dragons and fly to the rescue. Snowdrop continues to battle the alien and then she is almost killed, when suddenly Nightstar blasts him and Snowdrop resumes to battle the Predator. And she wounds him, and stabs him through the crystal floor, killing him.
Reuniting with Primrose/journey home/Snowdrop's lullaby
Snowdrop then feels something behind her. She looks back and sees it's Primrose. And Snowdrop hugs her with joy and then they all make their way out of Doom but when they get outside, they find that Doom has gotten a bit smaller than how it looked when they first entered it. And so they journey home, when they make it back to Canterlot. Primrose and Snowdrop then get ready for the night. As Primrose then explains about how she was worried about her. And then Snowdrop apologizes to her. And then asks about the Desk, and she said it was fine. Primrose then shares that she will being going back to the Desk, and asks Snowdrop to promise. Then she starts singing her own made-up lullaby and Snowdrop falls asleep as she fades away. And the film ends with "Wherever you are."
