The first slasher film to be set in prehistoric times!

When a tribe of cavewomen imparts cruel justice on one of their own, their fate takes a turn for the worst. After discovering and falling in love with the corpse sacrificed by the girl-gang, a lone wandering giant of prehistoric myths is inspired to homicide. Consequently, the cavewomen are menaced by the heartbroken and bloodthirsty cavebrute with a grudge, and the prophetess among them is ignored when she predicts the tragic outcome.—.
