Source plot synopsis — includes the ending
Three years later, a U.S. Senate committee debates whether Isla Nublar's dinosaurs should be saved from an impending volcanic eruption. Chaotician Dr. Ian Malcolm testifies that the dinosaurs should perish naturally to correct the wrongful cloning done by John Hammond. Meanwhile, Jurassic World's former operations manager, Claire Dearing, has established the Dinosaur Protection Group to save the animals. After the Senate votes against government involvement in rescuing the animals, Hammond's ex-partner, Sir Benjamin Lockwood, invites Claire to his Northern California estate. Lockwood and his assistant, Eli Mills, reveal a plan to relocate the dinosaurs to a new island sanctuary. Claire is needed to reactivate the park's tracking system to locate the animals, particularly Blue, the last surviving Velociraptor. She recruits Owen Grady, former Velociraptor trainer, to help locate Blue.
On Isla Nublar, Claire and ex-park technician Franklin Webb reactivate the online tracking system. Owen, paleo-veterinarian Zia Rodriguez, and a mercenary team led by Ken Wheatley, track and find Blue. The encounter escalates, resulting in Blue being shot and Wheatley tranquilizing Owen. Wheatley abandons Owen, Claire, and Franklin on the island while forcibly taking Zia hostage to treat Blue. A volcanic eruption begins, causing a massive dinosaur stampede and forcing the trio to escape. The ship, loaded with captured dinosaurs, departs as the remaining dinosaurs are left behind to die in the eruption. The trio sneaks aboard the ship and helps Zia transfuse Blue with Tyrannosaurus blood from Rexy to save her life.
The captured dinosaurs are actually being transported to the Lockwood estate, where Lockwood's young, orphaned 9-year-old granddaughter, Maisie, overhears Mills and auctioneer Mr. Eversoll secretly planning to sell the dinosaurs on the black market. They will also preview the Indoraptor, a weaponized, transgenic dinosaur created by geneticist Dr. Henry Wu using Indominus rex and Velociraptor DNA. Wu needs Blue's DNA to create an improved Indoraptor that follows commands, unaware that her blood is no longer pure. After Maisie informs Lockwood about the auction, he confronts Mills, who refuses to obey his orders and betrays him by smothering him to death with a pillow. Maisie is later revealed to have been cloned from Lockwood's deceased daughter and the reason why Hammond ended their association. The auctioned dinosaurs are being immediately shipped out. Franklin evades capture and frees Zia, but Owen and Claire have been apprehended. Owen incites a Stygimoloch into breaking open their cell. The two encounter and meet Maisie and learn the Indoraptor is being sold despite Wu's protests that it is a prototype.
Owen disrupts and ends the auction by luring the Stygimoloch into the room. In the ensuing chaos, Wheatley tranquilizes the Indoraptor to extract a tooth as a trophy, but the hybrid, feigning unconsciousness, kills him, along with Eversoll and others, as it escapes. The Indoraptor chases Owen, Claire, and Maisie throughout the mansion until Blue, released by Zia, attacks and fights it. After a standoff atop a high glass roof, both animals crash through it; the Indoraptor is killed after being impaled on a ceratopsid skull, leaving Blue unharmed. When a hydrogen cyanide gas leak threatens the caged dinosaurs, Claire attempts to free them by opening the cage doors. Owen convinces her not to open the subsequent outer door, but Maisie opens it to save them, reasoning that they, like her, have a right to live. As Mills attempts to escape with the Indominus rex bone, Rexy devours him and tramples the bone. Owen, Claire, Maisie, Zia, and Franklin escape, while Blue, Rexy, and all the other different species of released dinosaurs flee the estate grounds.
In a new U.S. Senate hearing, Dr. Malcolm declares the beginning of a new age, where humans and dinosaurs must coexist. The closing scenes depict the freed dinosaurs roaming the wilderness and outer urban areas.
