The Wicked (1980)

If your wife is seeing Dr Shinichi Toya, be worried ! This medico specializes in assisting women in removing both their husbands and their clothing. Every woman, except the wife he is currently divorcing, seems to adore him, and not all of them are very nice. The nastiest is probably his head nurse, who is an old flame trying to win him back, and who helps him get rid of the excess husbands. The not-so-good doctor gets away with quite a few of these apparently accidental killings, but he starts to become both greedy and careless.
