Barney Cashman, a middle-aged, married nebbish wants to join the sexual revolution before it is too late. A gentle soul with no experience in adultery, he fails in each of three seductions:
- Elaine Navazio, a sexpot who likes cigarettes, whiskey, and other women's husbands;
- Bobbi Michele, an actress friend who he discovers is madder than a hatter; and
- Jeannette Fisher, his wife's best friend, a staunch moralist.
