Jerry Miles, leader of a gang in the tenement district, is influenced to reform by Ruth Parker, who visits Jerry's lame sister, Kate. Later, Ruth's father, the Judge, runs for mayor. His political opponent, Black, by threats compels Jerry to steal for him certain incriminating papers from the Judge's library. Ruth catches him in the act. The gangster cannot explain himself without revealing to Ruth her father's crookedness, so he is silent. He is captured by the Judge's campaign leader, who leads him away out of Ruth's life forever.
