Twenty-seven years after their first encounter with the terrifying Pennywise, the Losers Club have grown up and moved away, until a devastating phone call brings them back.

Louis Creed, his wife Rachel, and their two children, Gage and Ellie, move to a rural home where they are welcomed and enlightened about the eerie 'Pet Sematary' located nearby. After the tragedy of their cat being killed by a truck, Louis resorts to burying it in the mysterious pet cemetery, which is definitely not as it seems, as it proves to the Creeds that sometimes, dead is better.
