The Shock Punch

Dan Savage wants his son, Randall, to be a real he-man, so he fits him for a business career by having him trained as a boxer. When Randall knocks out Terrence O'Rourke, he is delighted, and still more so when they take him to the Ironworkers' Ball to try out his newly discovered "shock punch". Randall knocks out Mularky, who is on a building job on which James Clark has staked his entire fortune. Learning that Clark's daughter, Dorothy, goes to the building each day, Randall gets a job as a riveter, discovers a plot to delay construction past the contract time, and ruin Clark; the chief conspirator being Mularkey, who was Randall's victim at the ball. Randall slips atop the building while trying to catch a molten hot rivet. While clinging by his very fingertips to the edge of a steel girder, Mularkey throws a white-hot bolt right in his face. He is saved by Giuseppi, who he has befriended, and he gets the Ironwork done before the time limit. Not to mention the girl too!
