Two German officers have new and differing plans for Stalag 13 --- both of which threaten Hogan's operations. In order to protect the camp and the gang's secret subterfuge, Hogan plays the two men against each other.

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.

Part 2 of 2. 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.

Hogan and his men make plans to lure Luftwaffe bombers within range of an allied anti-aircraft installation hidden in an abandoned warehouse, but Carter make a shamble of the plan when, while "leaking" the info to Klink, he forgets the name of the town where the strategic warehouse is located.

When the gang's hidden cache of money --- needed to purchase a secret map --- goes up in smoke, the men of Stalag 13 must come up with a way to replace the cash --- and decide to pull off a bank heist in the nearby town.

Hogan and his men are determined to create chaos during some staged war games a ruthless Nazi colonel has scheduled near Stalag 13. So what do you suppose would happen if the fake explosives planned for the exercises were somehow replaced with live ammunition?

The bumbling Sergent Schultz has unwittingly been conned into making a trip to Heidelberg as courier for the underground, but after upsetting Colonel Klink, the sergeant is ordered to remain grounded at the camp. How will Hogan and the gang win him a new weekend pass?

Klink becomes convinced that he is marked for assassination by a mysterious "Mr. X" after a series of close calls at the stalag. Could Hogan be behind the threats? Yes... but it's all part of a plan to masquerade as Klink in order to help a valuable underground agent escape from the camp!

A famed scientist is recruited by the Germans to develop a revolutionary new metal alloy for the Nazi war machine --- so Hogan and the gang must distract the doctor --- or worse --- to keep him from accomplishing his task.

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.

When Hogan and his men set out to destroy the Germans' new S-5 gun that's being guarded at Stalag 13, they uncover more then they bargained for --- a traitor amongst their ranks who has gone to Colonel Klink to report on Hogan's planned sabotage.

Hogan and his men face the difficult task of returning a Soviet pilot to his homeland --- especially when the fanatical, demanding Russian refuses to follow the usual escape route to England.

Hogan and his men have cleverly rigged the tabletop centerpieces to explode during a banquet for Germany's top generals --- unaware the one of the guests at the banquets is an invaluable spy working undercover for the Allies.

An American military captain and his crew hiding out at Stalag 13 face capture when Major Hochstetter and his search party zero in on the POW camp --- and its elaborate tunnel system to freedom is threatened with exposure.

Carter returns from an unsuccessful mission with a new pal in tow --- a runaway chimpanzee from the local bombed-out zoo. The men of Stalag 13 decide to make "Freddy" their barracks mascot --- but Hogan sees a more practical use for the happy-go-lucky chimp.

A German truck carrying an experimental jet fuel is the latest target for Hogan and the gang. But when all efforts to sabotage the shipment fail, Carter decides to get down to business with the remaining weaponry at hand --- a bow and arrow!

Hogan's plot to hijack a dynamite truck takes a different tack when the truck makes an unscheduled stop.
