In Stone Cove, Maine, sheriff's deputy Dwayne Hopper discovers Ronald Perkins in a holding cell. Perkins, a local pharmacist and suspect in the disappearance of fourteen children, including Hopper's son, reveals that he has assembled an army of brainwashed followers. As Hopper investigates, they unwittingly unleash chaos on the town. A night of terror ensues as super-strong, zombie-like warriors rampage through the streets, driven by one command: "Kill for Mr. Perkins."
