the scientists of the park create a new genetically modified dinosaur: Indominus Rex (I-rex for short), to attact more visitors. The I-rex is a hybrid not just out of carnivorous dinosaur DNA, but also of animal DNA (such as cuttlefish). However, before the new exhibit is about to open, the I-rex breaks out of his enclosure and starts rampaging a cross the island. Unfortunately for Claire, her two nephews, Zach and Grey, are visiting the park and are in the middle of one of the park's rides, "The Gyroshpere", when the I-rex attacks them. They survive the attack though, and are trying to escape from the island. Meanwhile, Claire and velociraptor trainer Owen Grady, are searching for the two boys to make sure they're safe. While this is going on, Owen and Claire, along with the rest of the "Jurassic World" staff, must stop the I-rex, before it terrorizes the park visitors.
