After a first attempt to sneak four underground leaders out of the German camp fails, Hogan and his men come up with a new plan: Convince the camp commanders, via radio broadcasts and newspaper headlines, that the war is over!

Hogan and the gang decide that the hapless Colonel Klink would be the ideal patsy to use to get an important list of agents safely to England --- with a little boost from Carter's masquerade as a ferocious German general with a fondness for duels.

Has Colonel Hogan finally snapped under the pressure of confinement? The men think so when Hogan suggests that, to rescue a captured British agent, the men of Stalag 13 take up basket weaving, tent making and kite flying!

LeBeau's weekly visits to an underground contact --- one he describes as a "mean little old lady" --- are revealed as something more after Hogan and the men discover that the "lady" is actually a beautiful young Dutch woman with whom LeBeau has fallen in love.

The clumsy and annoying Colonel Crittendon inadvertently messes up Hogan's plans to destroy a German ball-bearing plant.

Is love blind? Three beautiful German girls arrive at Stalag 13 and set the men's hearts beating faster --- but their mission is designed to pry secrets out of the love-struck POWs.

Shortly after Hogan helps a journalist escape to freedom, the Germans are amazed to read an American newspaper story about a sabotage-and-subterfuge unit hard at work right under their noses at one of their POW camps.

Hogan's scheme to kidnap General Burkhalter and trade him for an underground agent goes awry when Colonel Klink --- not the general --- is the one who gets kidnapped.

When Colonel Klink uses a beautiful baroness to try to wheedle secrets out of Colonel Hogan, he apparently falls under the femme fatale's charms. Or does he?
