Set in Marseilles, this is the story of Vanda, a beautiful woman in her thirties, arms covered in tattoos, skin so dark that some take her for a North African. Vanda dreamt of being an artist; she became a cleaner in a psychiatric hospital. Devoted to her six-year-old son Noé, she lives with him in a derelict shed by the beach. "You and me against the rest of the world," as she says. But when Noé's father Simon shows up after a seven-year absence, threatening the delicate balance of their lives, her suppressed rage finally explodes. The tension becomes unbearable, escalating to inevitable violence.
