Beautiful twenty-something, Justine (Melanie Laurent), an aspiring artist working full-time at a radiology lab, and the youngest of three sisters, has been plagued by failed relationships. After dumping yet another boyfriend, she moves onto the sofa at her sister’s place. Dom and her husband, having failed on countless occasions to produce a child, are planning to adopt. Meanwhile, the women’s tactless and selfish 60-year-old father, Eli (Michel Blanc), announces to the family over dinner that his much younger third wife is pregnant. It is to be his first child since Justine.
This is a film that chronicles the complex disturbances that have caused unrest within the family, and the miracles and tragedies that bring them closer together over the course of the film. Dom is desperate for a child, and while Eli’s wife is overjoyed by the prospect of a new addition to the family, he seems to be indifferent, more concerned with befriending Justine’s exes (a couple of them work for him) and improving his golf game. He retires, leaving the business in the hands of his younger associates, but during his twilight hiatus, manages to insult and upset his entire family, before learning (completely by chance) some debilitating news about his health.
