After their ship gets caught in a mysterious storm, the PAW Patrol pups crash land on an uncharted tropical island filled with dinosaurs. 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 PAW 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 PAW Patrol 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.
