Dan, the Irish Terror, is attracted by the charms of Hot Dog Hattie, but she does not care for him, as her affections are set upon Battling Bull. Both are members of the Stock Yards Athletic Club, and Dan sends Bull a challenge, which is accepted. Dan decides to get a line on Bull's work. He goes to his training quarters, climbs up on a box and peeps through the transom. What he sees there disconcerts him so much that he kicks the box away from under him. The Bull sees him and shuts the transom on his fingers. But Dan escapes. The day of the fight arrives. Dan has arranged for some dirty work, which fails to operate against Bull, and Dan is knocked out. Dan sneaks away from the ring, and takes the gate receipts. He takes them to Hattie, who shuts her up in her own hot-dog booth, and pushes it off down the steep grade of the street. He clambers on top of it and dresses himself there. The booth falls over a bank, and Dan rescues Hattie from the ruins. They are chased, but he manages to board a western-bound train with her. Bull finds a lone hot dog which tells him of her fate. Out west, Dan's prowess soon makes him master of the town. Hattie still dreams of Bull, and when he arrives in town in the guise of a tramp she recognizes him. Bull challenges Dan to another fight. Hattie disguises herself as a cow-puncher in order to be present. She pours glue on the seat in Dan's corner, and revives Bull with dope when he threatens to collapse. Dan is knocked out of the ring and chased down the street, while Hattie and Bull fall into each other's arms.
