Robert Warner, a big but timid man, is a victim of Bud Stevens, known as the “Bully.” Robert is in love with Kate O’Connor, whose father is a policeman, but he is too bashful to declare himself. Kate signifies her intention of going to work in the factory where Robert and Bud are employed, and, just as Robert anticipates, Bud shows him up to be a coward before Kate. To his mother Robert confesses his chagrin at the treatment he receives from Bud, and the mother tells him the story of his father who believed in using brute strength. Robert decides that he will not follow in his father’s footsteps. One night while he is calling upon Kate, Bud arrives and insults him before the girl and her father. This is too much and Robert decides that he will teach Bud a lesson, and, securing a gun, waits for him. He follows Bud for some distance and to his astonishment sees Bud receive, at the hands of his friends, the same treatment that he had given him. Later, he discovers the trio in the act of robbing a store and quietly takes Budd’s knife which he had inadvertently left near the window he pried open. The next day Robert uses the knife in the presence of Bud, who immediately demands his knife, asking Robert where he got it. Robert informs him that he picked it up from the place where Bud left it. Bud now realizes that Robert has the upper hand and persuades his companions that they should “clean up” Robert. Meantime, Robert has told Kate about the robbery and she in turn has told her father, so that when Bud and his companions call at Robert’s home they are taken in custody, and Kate decides that her love is for Robert.
