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 that the war is over!

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 Sergeant Carter constructs an amazingly complicated rabbit trap, a suspicious Colonel Klink comes to believe that the contraption is a secret electronic spying device.

With camp security raised, Hogan and his men are desperate to smuggle some top-secret photos of German fortifications to the allies. The solution? Make liberal use of Carter's remarkable impersonation of Adolf Hitler.

Hogan and his men play a part in the D-Day invasion of France when they are asked to create a diversion that will delay Colonel Klink and other German officials at Stalag 13 from retaliating once the invasion is underway.

Hogan gets Klink to believe he is about to bust a POW escape ring.

Klink takes Hogan to England to steal an Allied plane, but Hogan has other plans --- to expose some Nazi spies.

When he's captured in German uniform, Carter convinces the Germans that he is one of them.

At Stalag 13, a German prisoner-of-war camp, Colonel Robert Hogan and his fellow cohorts are a subversive group with many hidden talents. However, a spy has been planted amongst the men by the Germans.

In the first of a two-part story, "Tiger," a female underground agent, is arrested while trying to document some secret German bases and is held in Paris for questioning. So, Hogan and LeBeau become stowaways aboard Klink's staff car and head for Paris to free her.

While trying to free the underground agent "Tiger" in Paris, Hogan must seek help from a Parisian fortune teller, and also enlist the aid of a man who is a look-alike for Nazi Police Chief Heinrich Himmler.

An assertive General Burkhalter "requisitions" the famous Édouard Manet painting, "The Fife Player," from the Louvre museum in Paris to give to Hermann Goering as a birthday present. Undaunted by the seeming impossible logistics, Hogan and LeBeau decide to steal it back!

Masquerading as German workers, Hogan and the crew have made elaborate and foolproof plans to blow a German cannon factory sky-high, but their plan backfires when Newkirk winds up being drafted into the German army!

The heroes pose a Nazi officers to root out a German spy posing as an American pilot.

When LeBeau, Newkirk and Carter are captured by the Gestapo during a sabotage mission, Hogan must convince the affable Sergeant Schultz to impersonate the stern Colonel Klink and demand their release.

When an Italian POW camp commander arrives at Stalag 13 to train under Colonel Klink, Hogan and his gang try to convince the new arrival to go to work for the Allies.

Two German officers have new and differing plans for Stalag 13, both of which threaten Hogan's operations.

When an important Gestapo official wants to defect, Hogan brings him to Stalag 13, and convinces Colonel Klink that the fugitive is Adolf Hitler in disguise.

Newkirk, Kinchloe and LeBeau must help Hogan thwart the Nazis' planned assassination plot against British Prime Minister Winston Churchill.

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 "old lady" is actually a beautiful, young Dutch woman with whom LeBeau has fallen in love.

Hogan is asked to immobilize the entire German 6th SS division—10,000 men—for two days, while the Allies organize a surprise attack. The task seems impossible, especially in the presence of the two stern Gestapo colonels who are filling in for a vacationing Colonel Klink.

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

After making arrangements to send her to England, Hogan begins to worry that his beautiful underground contact, Heidi, might actually be a double agent.

Hogan and his men join forces with an undercover agent and steal away to Berlin to nab a German defector who can compromise their entire operation at Stalag 13.

A defecting Field Marshal tailed by Major Hochstetter to Stalag 13 needs Hogan's help to get to England.
