After the park was destroyed and the island was evacuated, everyone was left of the dreadful memories of the accident. Five months later, things have changed for Claire Dearing and Owen Grady. They live together in the United States in a large house, fly on plane trips to see the boys, and have a balanced relationship. Well, somehow. The nightmares have gotten worse and worse for Claire. She feels so deeply responsible for the park being destroyed and the Indominous being created. And things are just as bad for Owen. He's lost his raptors, job, old house, and money is dropping for the two of them. But something awful has happened. Something so shocking that nobody could believe it. The Indominous Rex is still alive... And the rest of the dinosaurs have broken free from the paddocks and cages.
