The PAW Patrol pups crash land on an uncharted tropical island filled with dinosaurs after their ship gets caught in a mysterious storm. They meet Rex, a pup who has been stranded on the island for years and has become an expert in all things dino-related. When the Patrol’s archrival, Mayor Humdinger, begins recklessly mining in hopes of exploiting the island for its natural resources, he inadvertently causes a huge, dormant volcano to erupt. The pups are thrown into a series of high-stakes, dino-sized rescues bigger than anything they’ve done before, as they must stop Humdinger before everything on the island goes extinct.

The Owens sisters must confront the dark curse that threatens to unravel their family once and for all.
