Trapped by a cave-in, a group of spelunkers drew lots to see whose arm would be amputated to feed them. Rescue came mere minutes after the deed was done-and the unfortunate loser was driven mad by the experience. Five years later, the survivors start turning up murdered and similarly mutilated... leaving those remaining to try and outrace the killer before they share their fate. Drive-in shock staple stars Deborah Walley, Marvin Kaplan, Paul Carr, David G. Cannon. 89 min. Widescreen; Soundtrack: English Dolby Digital mono; Subtitles: English (SDH); featurettes.
