Donald Duck dances at the sight of military posters and envisions himself as part of the army. He merrily reports with his draft card and expresses a desire to be part of the air corps. First he must go through his physical examination, in which a bunch of partially-seen doctors give him a full look-over. Passing the tests, Donald is fitted for his uniform. Soon he's reporting for duty, and his sergeant is none other than Pete! Pete has some one-on-one training in mind for the duck. Donald's got to deal with pesky ants and his only defense is some potent perspiration.
