Jurassic World

Teenaged brothers Zach and Gray Mitchell visit Jurassic World, a functioning dinosaur theme park and resort on Isla Nublar, the original Jurassic Park site, for winter holiday. The trip is arranged by their mother for the boys to spend quality times with their aunt, Claire Dearing, who is the park's operations manager, while their parents are in the middle of divorce. The boys are disappointed when Claire assigns her assistant, Zara, as their guide while she is busy, but the boys evade Zara to explore on their own.

Elsewhere on the island, Owen Grady, a Navy veteran, has been training the park's four Velociraptors, Charlie, Delta, Echo and Blue while also researching their intelligence. Based on the raptors' ability to follow commands, Vic Hoskins, the head of InGen Security, believes that they can be used as military animals, an idea Owen and his assistant, Barry, strongly oppose.

Prior to its opening, park owner Simon Masrani and Claire inspect the park's newest attraction, the Indominus rex, a genetically-engineered dinosaur created by geneticist Dr. Henry Wu. Claire has Owen evaluate the enclosure; they had previously gone on a date but it did not work out because of their differing lifestyles. Owen warns Claire that the Indominus lacks social skills from being raised in isolation, making it more dangerous and unpredictable. When it appears that the Indominus has escaped, Owen and two park workers enter the enclosure. Able to camouflage itself and mask its heat signature, the Indominus suddenly appears. Owen survives the attack, but it kills the other two men before escaping into the island's interior. Owen tells Masrani to have the Indominus killed, but protecting his company's investment, Masrani instead dispatches a specialized unit to subdue it with non-lethal weaponry. After most of the unit is wiped out, Claire orders the island's northern sector to be evacuated.

While exploring in a gyrosphere vehicle, Zach and Gray enter a restricted area. The Indominus arrives and destroys the sphere, but the boys get away. Finding the ruins of the original Jurassic Park visitor center, they repair an old Jeep Wrangler and drive back to the park resort. As Claire and Owen search for the boys, they barely escape the Indominus. Masrani and two troopers hunt the Indominus by helicopter, but the Indominus breaks into the park's aviary to avoid the gunfire, releasing the pterosaurs Pteranodon and Dimorphodon that collide with the helicopter, causing it to crash and killing Masrani in the process. Gray and Zach find Owen and Claire at the park as armed personnel shoot down swarming pterosaurs with tranquilizers. Zara is carried off by several pterosaurs before falling into the park's lagoon and being devoured by its Mosasaurus.

Assuming command, Hoskins orders that the raptors be used to track the Indominus; Owen, forced to comply, leads the raptors by motorcycle. Upon finding the Indominus, the animals begin communicating with one another. Owen realizes that the Indominus has Velociraptor DNA, and it becomes the pack's new alpha, usurping Owen's dominance. The Indominus escapes as troops fire on it. The raptors wipe out most of the troops, but one raptor is killed. Hoskins has Wu and the dinosaur embryos helicoptered off the island to protect Wu's research. Owen, Claire, and the boys discover Hoskins packing up the remaining embryos at the lab, but a raptor breaks in and kills him.

Outside, Owen re-establishes his bond with the three raptors before the Indominus reappears. The raptors attack the Indominus, but two are killed. Claire releases the park's Tyrannosaurus rex and lures it into battle with the Indominus. The latter gains the upper hand until Blue, the surviving raptor, joins the fight. Overwhelmed, the Indominus is cornered at the lagoon's edge, where it is dragged underwater by the park's Mosasaurus. Isla Nublar is abandoned once again, and the survivors are evacuated. Zach and Gray are reunited with their parents; Owen and Claire become involved romantically.
