Two couples, undermined by frequent scenes, fall apart: the men, Richard and Bertrand, directors of an advertising agency, move into their office; soon Lucien, their main client and friend, suffering from the same afflictions, joins them in this new bachelor life. For their part, the women regroup and organize themselves: Victoire absorbs herself in her work as a decorator; Charlotte, long submissive to Richard's personality, raises her head and finds a job; as for Pascaline, she runs off with Tabard, her husband Lucien's groom, to start raising sheep. These three crises, combined with a series of twists and turns, bring unexpected results for each of the couples.
