Twenty-two years after the events of Jurassic Park, Isla Nublar, an island located off Central America's Pacific Coast, near Costa Rica, now features a fully functioning dinosaur theme park, Jurassic World, as originally envisioned by John Hammond.
This new park is owned by the Masrani Global Corporation, but attendance has been declining due to the lack of new attractions. Owen Grady (Chris Pratt), a member of the park's on-site staff, conducts behavioural research on the Velociraptors.
At the corporation's request, the park's geneticists create the Indominus Rex, a genetically modified hybrid dinosaur, to boost visitor attendance, but it soon breaks loose and runs wild throughout the park, forcing the staff to consider extreme measures to stop it.
