Paul Beaumont is a scientist who labored for years alone to prove his radical theories on the origin of mankind. Baron Regnard becomes his patron, enabling him to do research while living in his mansion. One day, Beaumont announces to his beloved wife Marie and the Baron that he has proved all his theories and is ready to present them before the Academy of the Sciences. He leaves the arrangements to the Baron. However, after Beaumont goes to sleep, Marie steals his key, opens the safe containing his papers, and gives them to the Baron. On the appointed day, Beaumont travels to the Academy with the Baron. He is aghast when the Baron, instead of introducing him, takes credit for Beaumont's work himself. After he recovers from the shock, Beaumont confronts him in front of everyone, but the Baron tells them that Beaumont is merely his assistant and slaps him. All of the academicians laugh at his humiliation. Beaumont later seeks comfort from his wife, but Marie brazenly admits that she and the Baron are having an affair and calls him a clown. Beaumont leaves them. Five years pass by. Beaumont is now a clown calling himself "HE who gets slapped", the star attraction of a small circus near
Paris. His act consists of his getting slapped every evening by other clowns, and includes HE pretending to present in front of the Academy of the Sciences. Another of the performers is Bezano, a daredevil horseback rider. Consuelo, the daughter of the impoverished Count Mancini, applies to join his act. Bezano falls in love with Consuelo, as does HE. Consuelo's father, however, is planning to restore the family's fortunes by marrying her to the wealthy Baron Regnard. One night, during HE's performance, he spots the Baron in the audience and becomes enraged. The Baron then goes backstage and begins flirting with Consuelo, which she does not like. The next day, the Baron sends Consuelo jewelry, but she rejects it. When her father leaves for a meeting with the Baron, Bezano takes Consuelo out to the countryside for a romantic meeting, where they declare their love for each other. Meanwhile, Count Mancini convinces the reluctant Baron that the only way he can have Consuelo is by marrying her. The Baron agrees, and discards the heartbroken Marie, leaving her with a check. Later, HE admits to Consuelo he, too, is in love with her. She thinks he is kidding and laughingly slaps him. They are interrupted by the Baron and the Count, who inform Consuelo she will marry the Baron after the evening performance. When HE tries to interfere, he is locked in an adjoining room, where an angry lion is kept in a cage. He moves the cage so that, when he carefully opens it, only the door to the next room prevents the lion from escaping. HE re-enters the other room through the only other entrance (making sure to lock it behind him) and reveals his identity to the Baron. HE threatens the Baron, but the Count stabs him with a sword. The Baron and the Count try to leave but, finding the main entrance locked, open the side door, releasing the lion. The animal kills the Count, then the Baron. However, the lion tamer shows up and saves HE from the same fate. HE goes on stage and collapses. Assuring Consuelo that he is happy and that she will be free to lead her own life, HE dies in her arms. (In the original Russian play, by contrast, HE poisons Consuelo and then himself, the Baron commits suicide afterward, and the Count survives.) ==Cast==
