Esmeralda, left alone after her husband's departure on business, decides to avoid the temptation offered by one of his employees, a handsome accountant, by visiting three college friends who are organizing a charity party in Rome. Although all of the friends have married well to attractive men, they experience feelings of restlessness. Luisa, who has succumbed to extramarital temptations, is being blackmailed by a gang of extortionists who have recorded her in an encounter in the back seat of an automobile. After trying unsuccessfully to help the extortionists rob the charity party's receipts, Luisa resigns herself to suffering the consequences of her infidelity. However, when her husband accidentally hears the tape he believes that one of his own lapses has been recorded and falls prey to the blackmailers himself. Luisa meets another lover and hands him a card on which she has written, "Do what you want but don't talk." Norma has recurring nightmares in which she is sexually assaulted by a huge, moustached stranger. Following the advice of her psychiatrist, she has an affair with a traffic policeman who resembles the man in her dreams. As her dreams persist, however, she resorts to seducing other men who resemble the phantom brute, and she encounters a squad of moustached policemen. Paola, normally shy, performs a striptease at the charity party and creates a sensation. Her husband, a public servant, is forced to give up his job, and he becomes his wife's manager and straight man as she turns professional. Esmeralda returns home to consummate the affair with the accountant, but she is relieved when her husband's arrival forestalls her indiscretion. Her fidelity is short-lived, however: her husband announces that he has more work to do and insists that she attend the races at Monte Carlo with the accountant.
