Jurassic Park tells the story of eccentric billionaire John Hammond, who secretly clones dinosaurs and builds an island theme park off the coast of Costa Rica. When Hammond invites paleontologist Alan Grant, chaos mathematician Ian Malcolm, and lawyer Donald Gennaro to inspect the park, it is already on the verge of disaster. A disgruntled programmer named Nedry shuts down the park's security systems to steal dinosaur embryos, setting off a catastrophic chain of events that leaves the island defenseless. With the electric fences disabled, the Tyrannosaurus rex escapes its enclosure and attacks the stranded tour vehicles, critically injuring Malcolm and sending Grant into the jungle with two children. As survivors struggle to restore power and contain the dinosaurs, key figures including Hammond himself are killed by the very creatures he created. The island is ultimately bombed into destruction by the Costa Rican military, but a haunting epilogue hints that some dinosaurs may have already escaped to the mainland.

The headline events of Jurassic Park's creation and catastrophic collapse.

Tina Bowman is attacked on a Costa Rican beach by a strange bipedal lizard that bites and scratches her face and arm.

Reports spread of infants across Costa Rica being mauled and killed in their cribs by small, chirping, three-toed lizards.

Lab director Dr. Stone shuts down the investigation when technician Alice Levin suggests the lizard specimen could be a dinosaur.

Dodgson meets disgruntled InGen programmer Nedry at a San Jose airport and gives him a fake shaving cream can to smuggle embryos.

The visitors step off the helicopter on Isla Nublar and see an entire herd of apatosaurs moving through the trees.

Hammond refuses Wu's proposal to replace the current dinosaurs with safer, more docile versions before the park opens.

Arnold shows the tour group the control room, demonstrating a tracking system that monitors all 238 dinosaurs across the island.

The T-rex emerges from the trees during the tour and kills a tethered goat in front of the watching visitors.

Grant discovers a piece of velociraptor eggshell near the stegosaurus enclosure, suggesting the dinosaurs are secretly reproducing.

Arnold runs the dinosaur tally at Malcolm's insistence and discovers there are 283 animals instead of the expected 238.

As the T-rex approaches, Ed Regis abandons Tim and Lex alone in the locked Land Cruiser and flees into the jungle.

A stampede of dinosaurs overwhelms the surrounding terrain, forcing Grant and the children to climb a tree to survive.

Grant uses syringes of biogenic toxin injected into dinosaur eggs to poison and kill the remaining raptors in the hatchery.

Before the catastrophe at Jurassic Park, a series of warning signs appear along the Costa Rican coast as strange lizards begin attacking locals, though officials dismiss the threat. At the park itself, cracks in Hammond's vision are visible from the start: the staff is overwhelmed, the dinosaurs are secretly breeding, and Hammond stubbornly refuses advice to make the operation safer. During the tour, visitors witness the T-rex's raw power firsthand and discover that the animal population has grown far beyond what the control room's computers account for. When the crisis strikes, individuals like Ed Regis reveal their true characters under pressure, while others like Muldoon rush into the jungle to rescue stranded survivors. As chaos spirals, Grant and the children face a terrifying dinosaur stampede while the control room scrambles to manage the mounting disasters. The pool ends with Grant personally eliminating the last raptors in the hatchery, one of several desperate acts needed to bring the island's violence to a close.

The warnings, clues, and secondary crises behind the disaster.

Gutierrez finds a partially eaten lizard matching Tina's description on the beach and suspects it may be an entirely unknown species.

Alice Levin faxes Grant an X-ray of the lizard remains, and Grant immediately identifies the skeleton as a Procompsognathus dinosaur.

Rival company Biosyn holds a secret meeting and resolves to steal InGen's dinosaur embryos to create their own competing animals.

Tim spots what he believes is a juvenile raptor running freely through the trees outside the tour vehicles, but no one believes him.

Using night-vision goggles, Lex spots two raptors aboard a boat sailing toward the Costa Rican mainland in the distance.

Muldoon discovers the park's only working Jeep has been stolen from the parking lot, leaving no way to reach the stranded visitors.

Grant, Sattler, and Gennaro descend into the raptor nest underground and watch as all the dinosaurs suddenly bolt toward the beach.

A mysterious American man visits Grant at the San Jose hotel to report strange animals migrating across Costa Rica and eating crops.

The seeds of Jurassic Park's destruction were planted long before the power went out, beginning with suspicious lizard attacks on the Costa Rican coast that authorities refused to take seriously. Corporate espionage from rival company Biosyn motivated programmer Nedry to betray InGen, while Gennaro was warned before the trip that the island might need to be destroyed entirely. During the park tour, small but critical signs of breakdown appear — a raptor spotted loose in the trees, animals escaping to the mainland on a boat — that go unheeded until it is too late. When the T-rex attacks, Grant's expertise keeps him and the children alive while those around them make fatal mistakes, and Regis pays with his life for his cowardice. As survivors fight back against the raptors, Wu and Arnold are killed for underestimating the creatures they helped create, while Sattler nearly dies buying Grant the time he needs to restore power. The disaster concludes in the darkness of the raptor nest underground, and a haunting encounter in a San Jose hotel confirms that the crisis is far from over.
