Victor Schertzinger both wrote and directed this melodrama. John Corbin (Percy Marmont) works for years on an invention, only to have it stolen by Jonathan "Iron Man" Moore, an iron magnate (Hobart Bosworth). When Corbin's mother (Lydie Knott) dies of starvation, he sinks to the gutter. He receives help from Grogan, a saloon keeper (George Siegmann), and redemption with the help of Hope, a mission worker (Jane Novak). When a party of slumming youths come to the saloon, Corbin has to rescue one of the girls, who turns out to be Moore's daughter, Joy (Eva Novak). Although he sees a way to get revenge on Moore, Corbin hands the girl over so Hope can take her home instead. It's only then that he discovers that Hope, too, is the daughter of Moore. He goes to the Moore home to ask forgiveness and is shot by an attendant. While he is recovering from the wound, Moore comes to see the error of his ways and makes amends. Hope, meanwhile, is won over by the man she redeemed. Jane and Eva Novak were also sisters in real life.
