What does Dennis Nedry steal from Jurassic Park in the 1993 film?

Dennis Nedry steals dinosaur embryos from Jurassic Park in the 1993 film. Nedry, the park’s computer programmer, secretly agrees to smuggle the embryos to a rival company for payment.

To carry out the theft, Nedry disables the park’s security systems during a tropical storm. He takes the embryos in a disguised shaving-cream canister made by Barbasol. The container is designed to keep the samples cold and concealed while he transports them to the island’s dock.

Nedry’s sabotage causes the electric fences and other automated systems to fail. The resulting blackout allows several dinosaurs to escape their controlled areas and leaves visitors vulnerable. His plan collapses when a Dilophosaurus attacks him near his stranded Jeep.

The embryos are not dinosaur eggs. They are laboratory samples containing genetic material intended for InGen’s cloning program. The theft is one of the film’s central plot triggers, linking corporate espionage to the park’s catastrophic loss of control.
