Synopsis by Sandra Brennan
Heads are a poppin' everywhere in this Australian private-eye movie that combines elements of horror and science fiction. Dirk Trent is not the classic movie PI. He fat, clumsy, and nerdy. While tracking down a woman's unfaithful husband, his assistant films what at first seems to be the husband murdering his secretary in a cheap motel. Upon closer examination, Trent deduces that the husband didn't kill her because his head exploded first. Soon he discovers a whole series of people whose heads have blown-up. His investigations lead him to Dr. Henderson who has been conducting odd experiments to cure brain tumors.
