The literal translation of the decidedly squirmy black comedy's French title La Bouche de Jean-Pierre is "Jean-Pierre's Mouth," a reference made quite clear. The weirdness begins when young Mimi's mother attempts to kill herself. While her mother recovers in the hospital, she is sent to stay with her elderly, never-married Aunt Solange, who offers her a curtained corner in her tiny apartment. Much to Mimi's surprise Auntie Solange is a spinster but she is no desiccated prude, something the girl discovers when Solange's young, buff lover comes to call. Unfortunately, Jean-Pierre also finds himself shamefully attracted to the tender young niece.
