Having been trapped in the POW camp, René is enlisted in the plan to re-dig the tunnel, by getting rid of the dirt. Von Strohm and Geering are playing cricket, though not very well, and Herr Flick and Von Smallhausen are digging their own tunnel into the camp. Monsieur Alphonse arrives at the café to report to Fanny the news that René has been captured, but René and company join in on the British prisoners' plan to escape – though it will free only one man.
Dressed as girls from the Folies Bergère, the entire gang (the staff and the Germans) escape from the prisoner-of-war camp, and completely against plans bring the two British airmen with them. Outside again, the Colonel finds that the Captain is missing; only his glasses are found.
Since Maria's disappearance, the café needs another waitress, but René and Edith have somewhat different ideas about who should fill the position, but finally Michelle of the Resistance brings tiny Mimi from another cell to be René's bodyguard.
The Gestapo suspects that the Colonel and the General are in on a plot to assassinate Hitler, so Herr Flick goes undercover as Private Irma Von Kinkenrotten and plants a somewhat bizarre daffodil-shaped microphone in the Colonel's office, where Gruber and Von Strohm are making plans to get rid of Bertorelli in some way.
There are still no batteries for the wireless radio underneath the bed of René's mother-in-law, so Michelle's newest harebrained scheme is to have René and Yvette powering it with the generator from a bicycle until the stolen batteries from a German miniature submarine are delivered.
The Germans arrest René, and the Colonel demands an explanation for the knockwursts with explosives in them. After a small lie, René is sent home with around a dozen knockwursts to hang in his kitchen.
