In rural Maine, Vic and Donna Trenton (Hugh-Kelly and Wallace) struggle to repair their crumbling marriage, while their young son Tad (Danny Pintauro) befriends a hulking, lovable, 200-pound St. Bernard named Cujo. With Vic away on business, Donna and Tad take their decrepit car to be fixed at the remote farm of their mechanic (Lauter). As their aging Pinto sputters to a stop and dies, Cujo appears. But the once docile dog has undergone a hideous transformation - and becomes a slavering, demonic, killer possessed by almost supernatural strength...and unholy cunning. Critically acclaimed, CUJO is a fearsome, spine-chilling tour de force from the most popular name in horror!
