When Louis (Melvil Poupaud) dies of a drug overdose in Paris, his wealthy mother instructs his strung-out but pregnant girlfriend, Mousse (Isabelle Carré), to get an abortion. Determined to keep her child, Mousse flees Paris for a country home. Louis's brother (Louis-Ronan Choisy) visits, and she develops a fascination with him that is both erotic and angry. François Ozon crafts an intimate portrait of an enigmatic woman seeking a purpose.
