That's Adultery

In this zany comedy, four situations involving adultery provide fuel for laughter. A young man's skill at impersonating his boss gets him into bed with his boss's wives in the first segment. In the second, a Japanese woman commits adultery. The third concerns a couple who resume their relationship after one of them marries another. In the fourth, a woman is blackmailed by a third party who photographs her having sex with her lover while her husband is away. His price is to have a sexual relationship with the unfaithful wife.
