Thomas and Twilight Sparkle's Adventures of Furious 7 is the seventh upcoming Thomas/MLP:FIM/Fast & Furious crossover to be made by Hiatt Grey. And is the sequel to Thomas and Twilight Sparkle's Adventures of Fast & Furious 6.
After defeating Owen Shaw and his crew, along with Queen Chrysalis and securing amnesty for their past crimes, Dominic "Dom" Toretto, Brian O'Conner and the rest of their team have returned to the United States to live normal lives again. Brian begins to accustom himself to life as a father, while Dom tries to help Letty Ortiz regain her memory. Meanwhile, Owen's older brother, Deckard Shaw, breaks into the secure hospital that the comatose Owen is being held in and swears vengeance against Dom and his team, before breaking into Luke Hobbs' Diplomatic Security Service (DSS) office to extract profiles of Dom's crew. After revealing his identity, Shaw engages Hobbs in a fight, and escapes when he detonates a bomb that severely injures Hobbs. Dom later learns from his sister Mia that she is pregnant again and convinces her to tell Brian. However, a bomb, disguised in a package sent from Tokyo, explodes and destroys the Toretto house just seconds after Han, a member of Dom's team, is killed by Shaw in Tokyo. Dom later visits Hobbs in a hospital, where he learns that Shaw is a rogue special forces assassin seeking to avenge his brother. Dom (along with Princess Celestia and Princess Luna who had heard about Shaw's intentions) then travel to Tokyo to claim Han's body, and meets our heroes, and races Sean Boswell, a friend of Han's who gives him personal items found at Han's crash site. As Thomas tells Dom that it was all their fault that they couldn't save him in time, but after our heroes talk to him, Thomas regains his spirit and want's to avenge Han as the others do too.
Back at Han's funeral in Los Angeles, Dom notices a car observing them, and after a chase, confronts its driver, who is revealed to be Shaw. Both prepare to fight, but Shaw flees when a covert ops team arrives and opens fire, led by Frank Petty, a man who calls himself Mr. Nobody. Petty says that he will assist Dom in stopping Shaw if he helps him obtain God's Eye, a computer program that uses digital devices to track down a person, and save its creator, a hacker named Ramsey, from a mercenary named Mose Jakande. Dom, Brian, Letty, Roman Pearce, and Tej Parker then airdrop their cars over the Caucasus Mountains in Azerbaijan, ambush Jakande's convoy, and rescue Ramsey. The team then heads to Abu Dhabi, where a billionaire has acquired the flash drive containing God's Eye, and manages to steal it from the owner. With God's Eye near telecommunications repeaters, the team tracks down Shaw, who is waiting at a remote factory. Dom, Brian, Petty and his team attempt to capture Shaw, but are ambushed by Jakande and his men and forced to flee while Jakande obtains God's Eye. And then Cadance noticing Luna rubbing her stomach, and she asks her what is it, Luna then nervously tells her she's pregnant, but before she can explain how she got pregnant, she goes in labor! And so, she and Celestia are forced to leave, but Cadance decides to go with them. At his own request, the injured Petty is then left behind to be evacuated by helicopter, along with the Princesses while our heroes, Brian and Dom continue without him. Left with no other choice, the crew returns to Los Angeles to fight Shaw, Jakande and his men. Meanwhile, Brian promises Mia that once they deal with Shaw, he will retire and fully dedicate himself to their family.
While Jakande pursues Brian and the rest of the team with a stealth helicopter and an aerial drone, Ramsey attempts to hack into God's Eye. Hobbs, seeing the team in trouble, leaves the hospital and destroys the drone with an ambulance. Ramsey then regains control of God's Eye and shuts it down. Meanwhile, Dom and Shaw engage in a one-on-one brawl on a parking garage, before Jakande intervenes and attacks them both. Shaw is defeated when part of the parking garage collapses beneath him. Dom then launches his vehicle at Jakande's helicopter, tossing Shaw's bag of grenades onto its skids, before injuring himself when his car lands and crashes. Hobbs then shoots the bag of grenades from ground level, destroying the helicopter and killing Jakande. Dom is pulled from the wreckage of his car, believed to be dead. As Letty cradles Dom's body in her arms, she reveals that she has regained her memories, and that she remembers their wedding. Dom regains consciousness soon after, remarking, "It's about time".
Meanwhile, back with the royals, Luna gives birth to an alicorn filly! And once that, they hurry to find the team. Shaw is taken into custody by Hobbs and locked away in a secret, high-security prison. At a beach, Brian and Mia play with their son while Dom, Letty, Roman, Tej, and Ramsey observe, acknowledging that Brian is better off retired with his family. And then Luna explains that she's been pregnant shortly after the battle with Tirek and Thanos, and wanted to surprise Hiro until now. And she decides to call her "Moon Starlight".
Dom silently leaves, Ramsey asks if he's gonna say goodbye. Dom says, "It's never goodbye." He drives away, but Brian catches up with him at a crossroad. As Dom remembers the times that he had with Brian, they bid each other farewell and drive off in separate directions.
