La Glu tells the story of a woman, separated from her husband, and of evil reputation, who at a summer resort tries to capture the fortune of a wealthy aristocrat whose nephew had been in love with her, and is herself caught in the toils of her interest in a poor and primitive Breton lobster-fisherman. His simple soul discovering the past career and the heartlessness of the Parisian woman, in despair he tries to kill himself by throwing him-self on the rocks. When the Glu, the name given to the woman in question, tries to see the youth, his mother kills her with a mallet on the steps leading to the room of the invalid.
