Laurent (Alain Chabat) and Loli (Victoria Abril) are a thirty-ish married couple living in southern France with their young children. He is an estate agent; she is a housewife. Laurent has extramarital affairs.
Loli is unaware that her husband is unfaithful. Then one day, a campervan breaks down in front of their house. The driver is Marijo (Josiane Balasko), a 40s-ish butch lesbian who works as a DJ. She asks to use their phone. Loli has a blocked sink, so in exchange for using the phone, Marijo gets Loli's drain back in working order. Loli and Marijo begin an affair. Laurent is upset, but then his friend Antoine (Ticky Holgado) accidentally reveals Laurent's philandering to Loli. This seems to justify her romance. Marijo moves into the house.
Antoine then suggests that Laurent let Loli have her way, cease all hostility, and wait for the affair to burn out. Laurent agrees, and the household becomes a seemingly idyllic ménage à trois. But his strategy has its effect, especially after another lesbian couple, old friends of Marijo, happen by. Laurent welcomes them, but Loli becomes annoyed and jealous.
Marijo decides that the situation is not really going to work. She knows that Laurent wants her to leave. While Loli is away on a trip, Marijo makes a deal with Laurent. She will break up with Loli and leave immediately, if Laurent will give her something she has wanted for years: a baby. Laurent has sex with Marijo to get her pregnant, and Marijo departs before Loli returns. Laurent tells Loli nothing, as agreed with Marijo.
Laurent and Loli settle back down to their old life, but their relationship has been deeply affected. Then Loli hears from a mutual acquaintance that Marijo is living in Paris and is several months pregnant. Loli is astonished and shocked. She insists that she and Laurent go to Paris and contact Marijo. They find her working as a DJ in a lesbian dance club. Their intrusion provokes a quarrel with the club owner, who fires Marijo. Loli and Laurent take her back to their home, where she has her baby.
The ménage à trois is re-established, with the two mothers caring for their children. As a final twist, a handsome man (Miguel Bosé) moves into the neighbourhood and he and Laurent gaze into each other's eyes...Victoria Abril as Loli

Josiane Balasko called making a film involving lesbianism "a difficult challenge, since all I had as references on the subject were movies made mostly by men about men; male homosexuality has been shown on the screen thoroughly, unlike lesbianism, which has been kept silent and taboo."
The film was presented to the Chicago International Film Festival, in October 1995.
With her nomination to the César Award for Best Director, Josiane Balasko is the sixth woman in history to be nominated in this category, after Ariane Mnouchkine, Agnès Varda, Coline Serreau, Christine Pascal and Nicole Garcia.
