In the Bellinsky family there is Salomon, the father, full of life although the world would like to bury him too quickly; Geneviève, the mother, who is slowly slipping into quiet madness; Sarah, their daughter caught between separated parents who patiently tries to build her life with François, her fiancé.

Salomon, almost 80, tries at all cost to enjoy each moment. Fleeing his past, the war, the dead, his exterminated relatives, he throws himself body and soul into a quest to find one or several female friends to sweeten his final years, He is learning to tap dance, under the high patronage of Fred Astaire, and energetically refuses to embody the clichés of old age imposed by our society. It is at this point in his life that he meets Violette.

Meanwhile, Geneviève dreams of only one thing, to peacefully pursue her infantilization in the company of her home helper, protector, and guardian angel, Mr. Mootoosamy. She has slowly decided that the constraints of reality are too much of a burden and takes wicked pleasure in doing whatever she wants, which is to say, not a lot. Unfortunately her finances are at their lowest ebb and, encouraged by Mr. Mootoosamy, Geneviève is obliged to emerge from her torpor and to act.

Lastly, for Sarah, life is complicated. She finds it hard to find the right place between her father, whom she idolizes even though he annoys her, and her mother, who she can't understand. Just when she thinks that she's found a kind of stability with François, she discovers with amazement that she's pregnant, despite the sterility with which she'd been diagnosed by several doctors.

Caught off-guard, it is now Sarah's turn to create a family.
