Sinister 2 follows a single mother and her twin sons who move into a rural farmhouse that is haunted by the ghostly children from the previous film. As they uncover a series of chilling home movies, they realize it's not just a ghostly presence they have to worry about, but a sinister supernatural entity that possesses the children, driving them to commit acts of violence. A private investigator and a determined deputy also join the hunt to stop the evil spirit before it's too late.
