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.
