Stalag 13 becomes the site for a German counterfeiting factory that will produce both American and British currencies. But Sergeant Schultz's sticky fingers inadvertently tip Hogan off to the scheme when Schultzy spends some of the "funny money" gambling at the prisoners' casino.

Hogan's surreptitious operation --- as well as secret information on America's atom bomb project --- is threatened when it's discovers that a top Gestapo official knows all about Hogan's espionage activities and plans to offer him a deal.

"Kinch" agrees to fight a German boxing champ to divert attention from a heist that Hogan is planning.

Hogan convinces Klink that he is a great artist so he can smuggle out some maps in the Kommandant's canvases.

When Schultz is put in command, his mania for power jeopardizes Hogan's plan to smuggle uranium to London.
