Two women, two worlds: Betty, a talented young writer discovering the joys of motherhood with her four-year-old son Joseph; Carole, a waitress in a shopping mall bar, whose tough existence makes her harsh and indifferent to her son José. Their worlds have nothing in common, and there is no reason for them ever to connect, if it weren't for Margot, Betty’s mad mother who suddenly reappears after a long absence. When Joseph dies in a tragic accident, Margot concocts a crazy plan, as only she can, to prove her love to her daughter. Fate then leads these three women down a path full of suspense, right up until the final breathless moment. A powerful story of three mothers going through emotional upheaval, the film is also a psychological thriller, but above all, a hymn to maternal love and the triumph of the desire to live.
