How couples unite, interact, separate, reunite or find other partners. The links in this chain begin with Christian and Nathalie, who are coworkers and friends. Christian discovers that his lover Francoise is having an affair, and Nathalie advises him to give his feelings some time to heal, about two years. Nathalie is angry that her lover Mark does not want to see her more often, while he is jealous of the men in her past. Meanwhile, Francoise finds out that her new lover is not that interested in her anymore, and after they split, she encounters him with someone else. As romance fluctuates like the lunar tides, the myth of one true love takes a beating.

Louis is a family man, with a wife and young daughter, who discovers in mid-life that he is gay.

In this romantic farce, former opera-singer and current music festival organizer Hermance (Judith Magre) is married to Charles-Henry (Jean Roquel). However, she still has a passion for her former lover Simon (Carlo Brandt), but he has a thing for Francoise (Sabine Haudepin). Meanwhile, Nathalie (Tonie Marshall) keeps trying to put the moves on Hippolyte (Jacques Bonnafe), who is either unaware of or is ignoring her efforts, while her lackluster former lover Christian (Michel Gauthier) looks on and stays out of the whole mess. Who comes out the worst in this deal? Naturally enough, it's Christian, the fellow who has, for good or ill, kept the most distance from it, when Hermance, who seems jealous of everyone, tries to get even with Simon for running off with Francoise. Don't worry, it's supposed to be confusing.
