The Stooges are discharged from the army after WW I, and promptly administer some revenge to their mean sergeant. Years later they wind up in the army again, and of course the same sergeant is their superior. The sergeant plays various tricks on them, and when the Stooges go crazy with a cannon, blowing up a house, a bridge, and a smoke stack, he blows them up.

The boys are stowaways on a train box-car filled with furniture bound for Hollywood where they hope to break into movies and become stars. Arriving at the Carnation Pictures Studios. Fuller Rath, the studio general manager, receives a telegram from the home office telling him that a certain "Mr. Smith and his two assistants" will arrive to take over the supervision of the studios. He mistakes the Stooges as the executives and gives them free reign over the studios, where they proceed to disrupt and destroy the production of a romantic drama.

Set in the civil war, the stooges are spies for the north. They impersonate southern officers and infiltrate the enemy ranks to get valuable information. On the run when they are discovered, they hide in a cannon and are blown back to their northern headquarters.
