A Sergeant from I-corps is unable to pay his poker losses. In order to stay in the game, he offers to promote the doctors. They choose not to but ask if he can promote Radar. He goes from Corporal all the way to Second Lieutenant. This is funny at first, but soon his life begins to become complicated. All the things he enjoyed being an enlisted man start to unravel. He gets no respect from other soldiers or from fellow officers. He even loses his clerk's job to Klinger, who is utterly incompetent. He has developed a relationship with a nurse and she now rejects him. It is a clever idea and it works well as Gary Burghoff does his usually fine job as the frenetic little guy.
