In 1977, teenager Wayne gathers his two friends, female runaway Rhonda and disco club hopper Tim, for a drug party located in the suburban home of quiet recluse Dean. But unknown to Tim and Rhonda are the horrible secrets that lie in Dean's basement storage room. Dean is the uncaptured child murderer who uses his basement as a torture dungeon with the help of Wayne and fellow teenager David. When the drugs and alcohol mix get higher throughout the night, not even so-called friends are safe from the sadistic bloodlust of Dean.
