Elsa, a solo mom, can no longer get by and offers her best friend Juliette, also a mother and head of the family, to share an apartment. However, they need a third roommate. Elsa finds Matthieu, a lifeguard that Juliette has already met who has just separated from his wife and who wants to find an apartment so that she can see his daughter. Elsa, for whom the roommate can only be done between friends, discovers that Juliette and Matthieu are going out together and is against it.

A year of living together already and everything is going wonderfully for our atypical family of roommates ... Until Elsa realizes that she is pregnant ... Good news that Antoine, her ex-shrink and current lover, is not taking it easy ... Too bad, Elsa will do without him: raising a child alone, she knows how to do it! But furious at his inconsistency, Gaël suddenly demands to meet his biological father .... And, against all odds, the reunion between his mother and Maxime is like a second love at first sight ...

Virginie and Paul (her new boyfriend, son of a lesbian mom) announce that they are getting married! The too young lovebirds are of course in reaction to their unusual family models, but no one saw it coming! Juliette takes it very badly, especially as Elsa, delighted, offers to offer the festivities. Would the emancipation dreamed by Virginie run smoothly? Matthieu plays the top models to finance the resumption of his studies, Elsa forges another very strong female friendship and Juliette can no longer resolve to be reasonable. From unprecedented clashes to heated family dinners, a question emerges: can we preserve our friendships, our loves, our filial relationships when we live in a shared apartment and everyone believes they have a right to the chapter?

The roommates arrive in Marrakech in a riad that Françoise, Mathieu's mother, frequents from time to time! Well, that's what they believe ... Without saying it, the very young granny sold her Parisian apartment and bought the riad. She is counting on these family vacations to gently confess the truth: she lives there and even makes perfect love with Youssef, a widowed architect, fifteen years her junior. Once seduced by the magic of the place and the personality of her lover, her son Mathieu and the family at large can only adhere to her new choice of life! Unfortunately, taking gloves turns out to be more complex than expected.
