Amy’s younger sister names the dog Rover.

They take Rover into their house, their family. And once he’s there … he doesn’t want to leave.

Amy loves dogs. But she starts to worry when strange things start happening in the house.Objects move. Lights go off. Accidents happen.

Soon man’s best friend has turned into Amy’s worst nightmare.The problem isn’t Rover’s bark or his bite - it’s even creepier than that. This dog’s purpose is evil … and if’s waiting to be unleashed.
