Marion Moore's sweetheart, Frank Kenyon, a young author interested in social reform, discovering that Marion's father is the owner of the worst factory in the city, pleads with her to persuade him to make better working conditions. Marion refuses. The season's society event is an entertainment for the benefit of the Belgian War Victims. Marian is to play "Humanity." That day, Mina, a child working in the factory, has her hand mangled in a machine. Frank learns of the accident from Bud and determines to bring the lesson home to Marian. He bribes her chauffeur to drive Marian to Mina's home. Marian is forced to enter the house with him. They find Mina alone and almost unconscious from an overdose of an opiate. The only hope of saving the child is by keeping her awake until he can summon medical aid. He orders Marian to walk the girl until he returns. Then he dashes away in the machine.
