In the studio where the famous director Eric Von Berg reigns, Pierre Vanier, the male star of the film and the lover of Berg's muse, dies while rehearsing a scene. Over the course of a tangled investigation, the culprit is unmasked. This honest dresser is the adoptive mother of Vanier's wife, too unhappy with such a husband. The inspector, moved, concludes a suicide.
