James Morley, superintendent of the Crown Hill oil refinery, is unable to cope with the rough element in the works. Jack Hartway asks for a position, and Mr. Hastings discharges Morley. Hartway is duly installed as the new superintendent, and his first act is to put up a sign that Rooney, the bully, has formerly resented. Rooney tears the sign down, goes to the office to confront Hartway, is knocked down, and is made to nail the sign up again. But Rooney swears revenge, and sends his tool, Old Grogan, to Hartway with a note, telling him to leave town in twenty-four hours. Hartway only laughs at the implied threat, and answers that they can go "as far as they like." They plan to have Old Grogan fire the works. Hartway has met Hasting's daughter and fallen in love with her. He is spending the evening with her, when he hears that the plant is on fire. Hartway rushes away. He finds Rooney in a saloon, accuses him of the crime, and Rooney tries to escape, but is overtaken by Hartway and given a thrashing. Jack is about to be knocked down by two of Rooney's gang, when Mabel, who has seen the fight, shoots one of them. They get away, but Rooney is arrested and sentenced to prison.
