Bobby’s patriotism is fired by a recruiting poster with a picture of Uncle Sam pointing right at him and saying “I Want You.” He hustles to an army camp near his home and tries to enlist, but the officers, moved by his earnestness, tell him he can do more for the Colors by staying at home and watching the Pacifists, who are active in Bobby’s home town. Then Bobby tries to get into the Home Defenders, composed of boys and young men, but he is only eight and not tall enough, although he strains on tip toe to impress the examining officers with his height. Discouraged, he wanders away and overhears a group of Pacifists urged by a German to blow up a factory. Bobby follows them after dark to the factory, which they enter and plant a bomb. Bobby, as soon as they depart, stamps out the fuse and telephones the police. The German returns to see why the bomb has not exploded and starts to strangle Bobby, despite the protests of the Pacifists. The police arrive just in time to save Bobby’s life and arrest the Pacifists and the German. When the news of what Bobby has done is known about town, Bobby is made a hero by the soldiers and the Home Defenders. The latter body marches to Bobby’s home, where the captain invests the boy with his own sword and cap and turns over to him the command of the company.
