Charlie Samson is a hard-working married bookkeeper in Manhattan, struggling to advance himself by attending night school to become an accountant. He has just learned his wife is pregnant with their first child, and worries whether he is ready for fatherhood. He and four co-workers throw a bachelor party for a fellow bookkeeper, Arnold Craig, who is about to get married. After watching explicit, short stag films at one member's apartment, they decide to go bar-hopping. Charlie is to be Arnold's best man.
Colleagues attending the party include the older married man, Walter, who has recently been diagnosed with asthma, and Eddie, a happy-go-lucky bachelor. The night becomes a turning point for all five men.
Charlie finds his loyalty to his wife tested during the evening, and he almost has an affair with a young woman he meets on the street heading to a Greenwich Village party. Charlie's young wife at home is also shocked to hear her visiting sister reveal her own husband's extra-marital affairs. Walter, in despair about his situation, wanders off during the evening.
