What could be scarier than an all-night HorrorthonInch? A group of film students finds out when they stage just such an event at an abandoned movie palace. In addition to the three features-MOSQUITO, THE ATTACK OF THE AMAZING ELECTRIFIED MAN and THE STENCH-they decide to screen a bizarre short called THE POSSESSOR, whose creator, Lanyard Gates, killed his family and set the theater on fire after it's first showing. Maggie (Jill Schoelen, THE STEPFATHER) has been having frightening dreams that seem to be connected to THE POSSESSOR, and as the festival proceeds, the nightmare comes true for her and her friends as they are stalked and slain by a mysterious killer. Has Gates survived to continue THE POSSESSOR's deadly legacy?
