The story opens with a prologue. In the prologue Jeff Davis meets a young fellow named Bill Stevens, who is beating his way to New York City. In the story proper, to New York City comes this young fellow. In another part of the city at the same time a beautiful young girl, Millie Browning by name, is anxiously trying to get employment. Her mother is sick. She is threatened with eviction for non-payment of rent. Accidentally, Stevens meets Tom Carroll, a yeggman. He needs a partner to help him in the job he has that night. Stevens is discouraged and listens to the yegg and is almost on the verge of accepting his proposition when Jeff Davis arrives on the scene. Jeff recognizes the yegg, a notorious character, and also Stevens, the young fellow he met on his way to New York. Jeff tells Stevens he is in bad company, and on the road to the “Bridge of Sighs,” so Stevens promises to stick to his search for honest work and to come to the Hotel de Gink if he fails. Meanwhile the yegg meets Millie Browning, and follows her from place to place as she seeks work. He follows her home, as he figures that she is hopelessly down and out and that she should be easy prey. Carroll sees her coming out and inquires for a mythical tenant of the house. He offers her work and conducts her to his headquarters, the back room of a saloon. Stevens, who has secured a job as porter in this saloon, sees the yegg with this beautiful young girl. Stevens is amazed to see an innocent young girl with the yegg. The yegg tells the young girl he is a detective, and the employment he has for her is as his assistant. She accepts the job, and he tells her it is absolutely necessary for her to disguise as a boy. The girl agrees to wear boy’s clothes. That night she arrives at the saloon disguised as a boy. Stevens meets her. His desire is to save the girl. She tells him she must have money, and tells him why. He promises to help her and she believes him. The yegg hears what Stevens said to the girl and puts up a job to send Stevens to the penitentiary. With another crook he plans to rob a safe and have Stevens caught in the act, but the timely arrival of Jeff Davis, “King of Hobos,” from the Hotel de Gink, saves Stevens from his first step in crime. After a number of sensational scenes, including a terrific struggle with the crooks and police, the story ends at the Hotel de Gink, where young Stevens and the girl see the sunshine of the future.
