On Friday the 13th, a teen obsessed with Satan and serial killers terrorizes a small Texas town. Survivors fight to stay alive as police race to stop him before dawn during a night-long rampage that leaves the town forever changed and scarred.
Police discover a family dead in their mansion. The scene includes a horror film flickering on a screen and a bloody mask nearby. A letter hinting at the demon from The Exorcist leads investigators to believe the case is more complex than a murder-suicide.
