The Unknown Lover (1925)

Elaine Kent weds Kenneth Billings, a young man who has a taste for wild living. She attempts to reform him and his exasperated father disinherits him. Now that he is without money, Kenneth starts a dye business and he proceeds to throw himself into it with the same amount of effort he once spent on the high life. As a result, he overworks until he is on the verge of a nervous breakdown.
