A landslide tears through a prehistoric wildlife reserve, destroying the electric fences and releasing a deadly Daspletosaurus into the campground. Ryan escapes into the forest with his son Noah, who suffers from severe asthma, but their only bag of emergency medicine is lost during the chase. As Noah’s oxygen begins to run out, Ryan must return to the dinosaur zone and join forces with his estranged wife, Claire. Together, they cross swamps, flooded rivers, collapsing bridges, and a dangerous pterosaur canyon to recover the last dose. With the predator still hunting them and every rescue route failing, the family is forced into a desperate flight toward the hospital. To save their son, two broken parents must trust each other again—and keep running until they make it home alive.
