Looking to turn a class research project into a party, a group of college students chooses Halloween night to explore the long-abandoned local insane asylum, but one killjoy they didn't count on was Smiley (Jed Rowen), the asylum's last surviving resident. As the malicious inmate makes his presence felt and the building's murderous past is exhumed, the teens discover that their only hope of escape is to head to the one room they don't want to visit.
