In this thrilling fourth installment of the "Jurassic Park" franchise, two young brothers (Ty Simpkins and Nick Robinson) visit their Aunt Claire (Bryce Dallas Howard) who's an executive at Jurassic World, a theme park populated with genetically resurrected dinosaurs. But chaos erupts when a newly created dino escapes its enclosure, forcing the park's animal behaviorist Owen Grady (Chris Pratt) to save the day. ~ Violet LeVoit, Rovi
