When Benton returns and finds his wife and Clark together, a fight ensues between the two men in which Benton is killed by The Weasel. Clark is accused of the murder and sentenced to jail, but escapes and joins the Navy. Meanwhile, Mary Ellen is forced to live in shame until she is rescued by Jane Murray, an office assistant in an East Side infirmary. There Mary Ellen meets Dr. Graham, Benton's cousin, and the two fall in love.

A newsboy informs the doctor of her whereabouts, and through the doctor's efforts Mary Ellen wins her freedom as well as his love.
