Forty years after directing and starring in a slasher movie, entitled The Dark Beneath, centred on a group of friends being killed by a masked killer, Ted Radford suffers a mental breakdown and is admitted to a psychiatric ward.
When another doctor, Dr Wayne, arrives at the ward the following morning, he discovers evidence of a mass slaughter, however no bodies are to be found.
The theater's staff, Bridget, Rachael, and Kenny welcome a small group of customers, including a biker couple, Harley and Babe, Dr. Wayne and Detective Barrons, who both believe Radford will appear, and Bridget's boyfriend Josh, who is with his friend Mario, Mario's girlfriend Samantha and their friend Sully.
Bridget, Josh, Mario and Samantha think of it as an elaborate prank by Sully, but Rachael too is stabbed to death for all to see, prompting everyone to investigate.
Bridget, Josh and Mario make their way back to the theater where they witness Babe being murdered on the screen.
They are ambushed by the killer's movie mother, but Timmy stabs her and they continue their escape, with Radford in pursuit.
Phase 4 would later re-release the film as a part of its Horror 4 Pack, which included The Attic, Carver, and Outrage Born in Terror on March 1, 2011.
