Why Leave Your Husband? (1920)

Dora West, the wife of a doctor, falls in love with Hilton, her husband's ward. Allowing it to be thought that she has drowned, Dora elopes with Hilton, who, quickly tiring of her and swamped with gambling debts, becomes secretly engaged to Lilla Ashley, the daughter of a rich and famous specialist. Dr. West, a colleague of Lilla's father, pays a visit to the Ashley house, prompting Dora to sneak into the house to see her little daughter. The resulting confrontations expose Hilton's double game, and Dr. West takes Dora back.
