A midnight screening of a 1970s cult horror film becomes a wholesale bloodbath after the members of the audience see one of their friends butchered on the big screen, and quickly surmise that there's a madman in the theater who seeks to slaughter them all. It was just another rundown movie house in a small suburban town -- what better place for a screening of a true cult classic? But this isn't your typical horror film, because years ago, the director had been locked away in a psychiatric hospital after having a complete mental breakdown. The teens at the screening have no idea that he escaped from the hospital nearly five years ago, and that chances are good he's still out there somewhere. When the film starts to roll and the heckling begins, the atmosphere in the theater is loose and fun. Giddiness gives way to deep-rooted dread, however, when the horrified audience is forced to watch as one of their good friends is viciously murdered right before their very eyes. This is no movie, and when the audience tries to flee they realize that the same psycho they just saw on the silver screen has now trapped them all in the theater. With no hope of escape and their numbers thinning fast, the survivors must now figure out a way to turn the tables on the very same killer that they once rooted for in their favorite slasher flick.
