Unbalanced Japanese geneticist (Tetsu Nakamura) injects American journalist (Peter Dyneley) with an experimental serum that turns him into a scary, hairy beast with a second head. Hijinx ensue. There’s a lot of heavy drinking in this film, enough to make you wonder if was meant as a commentary on the destructiveness of alcoholism. Also notable, at least in the Amazon Video streaming version, is the the abruptness of the ending. Wow!!!
