WWI has ended and stooges have been discharged from the service, even though they've done absolutely nothing. When their sergeant discovers this, he beats them up badly, but the stooges have their revenge and beat him up. Years pass by and the guys become bums. They try to steal a meal from a well-to-do man who chases and catches them in front of a military recruiting station. When the boys ask for a job, he tells them to go into a nearby building and go to room 310. They sign up, but it turns out to be the army, and they're under their old sergeant's command again! They are assigned to train on a big gun at a naval base, and after messing up many times, they accidentally fire on the Admiral's flagship. The sergeant then blasts them away by firing a cannon at them. 1936
