In Beverly Hills, California, former television actress Clare Lipkin pretends to mourn the death of her rich husband, Sidney. She hopes the tragedy will illicit a public outcry of sympathy and revitalize her career. Clare shares her sprawling estate with a precocious teenage daughter, Zandra, and a “thinologist” named Dr. Mo Van de Kamp, who moderates Clare’s caloric intake. Clare rejoices in her newfound independence, but her divorcée neighbor, Lisabeth “Lis” Hepburn-Savarian, is not happy to be out of wedlock. Lis’s husband, Dr. Howard Savarian, recently left her for another woman, and Lis is now the sole caretaker of their sickly adolescent son, Willie. However, Lis is cheered by a visit from her playwright brother, Peter Hepburn, and his lusty new bride, To-bel. The couple married after a weeklong, whirlwind romance, and Lis is jittery about the disparity in their social standing. When Lis hires a pesticide company to exterminate insects at the Savarian estate, Clare welcomes the divorcée and her extended family as weekend houseguests, even though she will be hosting her husband’s wake during their visit. Meanwhile, Clare’s handsome house servant, Juan, is pursued by a gangster named “June-bug” for a $5,000 gambling debt. Juan fears for his life and seeks advice from his close friend, Frank, who happens to be Lis’s valet. Wielding an envelope, Frank tells Juan that the package contains $5,000 and challenges his friend to a contest in which they will seduce each other’s bosses. However, it is a race to the finish, and Juan must bed Lis before Frank gets to Clare. Frank promises to give Juan the $5,000 if he can prove his conquest is well-timed, but if Frank is victorious, he must be rewarded by a night of sex with Juan. Although Juan is protective of his heterosexuality, he agrees to the bet. The next day, Juan and Frank pursue their respective employers, and Lis’s ex-husband, Howard, is brought to the house by police after being detained for public intoxication. Lis is not pleased about their reunion, and Peter Hepburn detests his former brother-in-law, but Howard is permitted to stay at the house for Sidney Lipkin’s wake because they were close friends. Howard is confronted by Peter’s new wife, To-bel, who reveals that she was the mistress who lured Howard away from his marriage. However, since Howard was also unfaithful to To-bel, she married Peter to jumpstart her quest for revenge. Fearing To-bel’s rage, Howard seeks refuge with his former wife, but Lis is not interested in reconciliation, so he enlists the services of his house servant, Frank, for support. On the day of Sidney Lipkin’s memorial, Frank convinces Lis to take pity on her ex-husband, and she invites Howard to her bedroom at midnight for conciliatory sex. Before the couple meet, however, To-bel tells Lis about her affair with Howard. Unsurprised, Lis remembers how Juan showed interest in her earlier that day and sets a trap for her deceitful husband. Lis beckons Juan to her room just before midnight and they make love as Howard arrives and realizes he has been cuckolded. Meanwhile, chaos ensues at the Sidney Lipkin memorial. Lis and Howard’s son, Willie, watches a pornographic videotape in a spare bedroom and discovers his new “Aunt To-bel” is actually an erotic film actress. The video changes hands and is mistakenly screened in front of the memorial guests, who are expecting to watch an episode of Clare’s popular television series. However, To-bel disconnects the electricity before she appears onscreen. When Willie confiscates the videotape and returns it to To-bel, she rewards him with his first sexual experience. To-bel leaves the boy to find Howard, who is still reeling from Lis’s prank. As To-bel and Howard rekindle their affair, To-bel’s husband, Peter Hepburn, vows his love to Clare and they spend the night together. Although Frank the valet is not successful at bedding Clare, he seduces her young daughter, Zandra. After an evening of strange couplings, the group reconvenes at a breakfast banquet, where awkward truths are revealed. Meanwhile, in the servants’ quarters, Juan refrains from telling Frank about his night with Lis because he has fallen in love with her, and does not wish to tarnish her elite social standing. Frank suspects his friend is hiding the truth, but plots to win the contest himself. He tells Juan to visit his room later that afternoon. When Clare abruptly ends her calamitous late-morning party, Frank invites her to his room, claiming that he will soon be leaving his post with the Savarians. With Clare in his chambers, he encourages her to share a toast and she agrees, unaware that he has spiked her drink with sleeping pills. As Clare slips into unconsciousness, Frank lifts her into his bed and simulates lovemaking. Juan arrives at his friend’s room as planned and watches from afar, realizing he has lost the $5,000 bet unless he admits to his liaison with Lis. Although Juan does not wish to remain in debt to the gangster June-bug, and dreads homosexual intercourse with Frank, he keeps Lis’s private affairs in confidence. At the end of the weekend, the pest extermination at Lis’s estate is complete and the house is untented. However, Howard Savarian does not return home. He puts a $100 bill beside his sleeping son, Willie, and leaves town with To-bel. Meanwhile, Clare decides to move away from the Lipkin mansion to pursue her dream of becoming a more sophisticated actress. She bids farewell to the bereft Peter, who has just lost his lover and his new bride. Clare’s daughter, Zandra, goes off with the “thinologist,” Dr. Moe, to fight world hunger in Africa. Elsewhere, Juan convinces Lis of his adoration, and they decide to run away together, but Juan makes good on his promise to Frank before they leave and he spends the night with his friend. As Juan packs Lis’s car, June-bug arrives to collect his $5,000 debt. Juan is empty-handed, but Frank rolls up on his motorcycle and tosses him the cash envelope wagered in their bet. Driving their separate ways, the two are liberated from domestic servitude in Beverly Hills.
