Jason Steel is an actor who plays a compassionate doctor on a popular TV drama. He is confused with his TV role and is so beloved that women won’t leave him alone, as evidenced by an all-women mob that surrounds him when he opens a new store. This, combined with him feeling that his show has gone stale, causes him a lot of stress.
Jason meets his poker buddies, Tom, Harry, Sanford, Yoshimi, and Leonard for a weekly Wednesday poker game. They discuss marriage, Jason saying that he and his fiancée, sculpture teacher Melissa, will show the others how great marriage is when they’re married. A woman calls then, asking for Jason, saying that she needs help. His buddies tease him when he says he has to go home to meet someone. They’re unaware that the women who call, asking for Jason, are their own wives.
That night, the woman is Jacqueline, Tom’s wife, who asks Jason for advice about the excitement leaving her marriage. Ecstatic that he listens, she kisses him; he repulses her and reiterates that she needs to talk to Tom. His valet, Charlie, overhears and believes that they’re having an affair.
The next poker night, Tobi, Harry’s wife, calls for Jason. She wants his advice about her marriage. He leaves to envious comments, and they meet at his house. Jason and Tobi dance, while he provides her advice. Again, Charlie, thinks that they’re having an affair. On-set, Harry tells a visiting Melissa that she shouldn’t keep Jason up so late, as it makes him worthless at work. She’s confused and argues with Jason when he asks her confusing questions and wants to postpone the wedding.
At the next poker game, after Jason’s called away, his friends are confused as to why he’s still “shopping” around when he has Melissa. At home, Jason gives advice to three friends’ wives in turn, speaking to Yoshimi’s wife, Isami, then Tobi, then Jacqueline, each of whom hides when the next woman rings the bell. Finally, a policeman rings. He noticed the activity and decided to investigate. His voice causes each woman to emerge, slinking away from the house.
A frustrated Jason schedules an appointment with Sanford, who’s a psychiatrist. Jason tells him their friends’ wives have been calling him, unwittingly giving him a wrong impression. He also admits that he’s worried that his marriage will be unhappy, like their friends’ marriages. After, Jason feels better and wants to marry Melissa. Stella, Melissa’s best friend and Sanford’s assistant, eavesdrops. Both she and Sanford believe that Jason’s been lusting after everyone’s wives; they panic.
Jason calls Melissa and confesses everything. However, Melissa’s wary of Jason’s neurosis, so agrees with a scheme of Stella’s: Melissa will “marry” another man, Sam, to force Jason’s hand. A few days later, Melissa confesses that her “marriage” to Sam was a mistake, and she’s left him. Jason tells Melissa that he wants to marry her, so she needs to divorce Sam. She tries to tell him the truth, but Stella lies that they’re flying to Tijuana for a “divorce.” Jason accompanies them and discovers that they tricked him. He leaves, heartbroken that the only honest woman he found lied to him.
Stella and Charlie talk him into talking to Melissa. He goes to see her, still angry, but demands that they marry that night.
