Jabbs, falling asleep at his club one evening, is made the victim of a practical joke by his fellow club mates, who relieve him of his watch. On his way home, he collides with Prof. E.Z. Mark, who, having been presented with a beautiful watch by his fellow professors, is naturally somewhat still under the influence of the happy event. Missing his watch, a minute later, Jabbs naturally suspects that the professor was none other than a clever pickpocket who had used the collision to cover up his light-fingered operating. Running back Jabbs catches up with the professor and after administering a severe beating to him forces the professor to hand over his own cherished watch. Not until the following morning when he reads of the robbery of which the professor is the victim does Jabbs realize his error. In terror that he may at any moment be arrested. Jabbs seeks several ways by which he can rid himself of the watch, which is plainly marked with the professor's name. All his schemes failing, he throws it out of the window to be found by Pokes who gives it to his sweetheart, Ethel, Jabbs' daughter who proudly displays it to her father. Jabbs employs a professional crook to rob his house. The crook forces Pokes to assist him in the robbery. They fight over possession of the watch and both are marched off to jail. Jabbs' home is demolished by the crook and Pokes. In despair he rushes out and seeing the professor calls to him to come and get the watch, but the professor, fearing another beating, hurries away. He is followed by Jabbs. The professor seeks refuge in the police station just as the crook and Pokes are being arraigned. The crook catches sight of Jabbs and accuses him of hiring him to rob his home and the professor also accuses him of being the man who assaulted him and robbed him of his beautiful watch. The evidence being conclusive all three. Pokes, Jabbs and the crook are led away to the cells, where the crook and Pokes proceed to mete out to Jabbs dire punishment for having been the direct cause of their predicament.
