Pet Sematary is a gripping tale of horror where the boundary between life and death is blurred. When the Creeds move into a beautiful old house in rural Maine, everything seems perfect: a physician father, a beautiful wife, a charming little daughter, and an adorable infant son, all complemented by an idyllic home. The friendly cat adds to the family's happiness, but the nearby woods harbor a chilling secret.

Behind the children's pet cemetery lies another graveyard, one from which the dead return. The Creeds are about to discover that sometimes, dead is indeed better, as they are drawn into a sinister world where the line between the living and the dead is frighteningly thin.
