40 years ago, the town conjured up a demon (Century) with disastrous results. Now they are about to conjure the demon again and are making the same mistakes all over again (some people never learn). Teenage Tess Hunter learns the truth and tries to stop a second disaster.
Anthropologist Dr. Brockton (Joan Crawford) unearths a troglodyte (an Ice Age 'missing link" half-caveman, half-ape) and manages to domesticate him - until he's let loose by an irate land developer (Michael Gough) to go on a rampage and kidnap a little girl. Crawford's last feature film.
