Sylvia Smalley is the secretary of Charles Edmay, a distinguished blind playwright. Leroux, a producer, is eager to buy the play that Edmay has just completed, but the playwright is reluctant to sell. Leroux sends Alice Morgan to steal the script while he abducts Edmay and Sylvia. While Edmay is detained in the wine cellar, Leroux exercises his hypnotic powers over Sylvia, extracting a dictation of the entire play from her. Discovering that in a hypnotic state Sylvia has great dramatic powers, Leroux successfully casts her in the play's lead. Her effort is too great, however, and she succumbs to exhaustion. Leroux awakens her from her trance, and, realizing what has happened, Sylvia reproaches him so harshly that he consents to release Edmay from the cellar. Leroux then plans a dramatic end to his life by entombing himself alive. At that moment, Sylvia awakens and realizes that the whole incident had been a dream triggered by nervous exhaustion.
