Prior to its opening, Claire and park owner Simon Masrani inspect the park's newest attraction, the "Indominus rex", a transgenic dinosaur created by geneticist Dr. Henry Wu. Masrani tasks Owen with evaluating the enclosure's security. Owen warns Claire that the "Indominus" lacks social skills, making it dangerous and unpredictable. When the "Indominus" has apparently escaped, Owen and two park workers enter the enclosure. The "Indominus", which can camouflage itself and mask its heat signature, suddenly appears. Owen survives, but it devours the other two men before escaping into the island's interior. Owen advises Masrani to have the "Indominus" destroyed, but to protect his company's investment, Masrani dispatches a specialized unit to subdue it with non-lethal weaponry, so it can safely be returned to its paddock. After most of the unit is slaughtered, Claire orders the evacuation of the island's northern sector.
