Vivie Warren, a student at Cambridge, comes to visit her mother in Surrey. She pursues a business career, but is unaware that her mother is the owner of several brothels throughout Europe. An older friend of her mother's, Sir George Crofts, falls in love with the young girl. She, however, is attached to the worthless young son of the parish rector, Frank Gardner.
When Crofts discovers that Frank's father was once a lover of Mrs. Warren, he breaks up the match between Vivie and Frank by telling them they are half -brother and sister. Frank doesn't believe Crofts, but when he learns of Mrs. Warren's true profession, he determines that he cannot marry Vivie. Vivie forgives her mother and goes off to London to make her own life.
