A murderous TV repairman, Horace Pinker is killing people in a small town left, right and center. He eventually finds the home of Lt.

His other son, Jonathan has a strange connection to Pinker through his dreams, and he directs his father to Pinker’s business, where a small group of officers enter. Pinker escapes in a horrific spree, killing four officers and then targeting Jonathan’s girlfriend, Alison. Another dream leads Jonathan and his dad to a residence where they catch Pinker in in the act of kidnapping. Pinker is arrested after a fight with Jonathan and sentenced to die in the electric chair. When executed, Pinker – who supposedly had given his soul to the devil in exchange for the power to come back as an energy source – takes over people’s bodies and continues committing murders, until Jonathan devises a plan to bring Pinker into the real world, and then cut off his power source…
