A terrible threat has escaped into Adventure Bay, threatening the very lives of its inhabitants. As the Paw Patrol struggles to maintain order, Chase finds himself clashing with the Assault and Containment Guild, a government team sent to lock down the town. When the threat begins to close in, the Paw Patrol is not just trapped within The Lookout, but forced to stare at true death in the eyes. One pup loses its sanity, another gains paranoia, one struggles to keep the team together, and one pup just may be carrying the threat itself. Will the Paw Patrol survive the lockdown? Or will they slowly be taken out, one by one?
