Having been trapped in the POW camp, René is enlisted in the plan to re-dig the tunnel, by getting rid of the dirt. Hans and the Colonel 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 only one person can escape in this way.

Meanwhile, Helga reports the situation to Gruber, and together they decide on a plan to rescue the Colonel, the Captain, and René, involving Gruber dressing as a nun.

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.

Herr Flick and von Smallhousen intercept a message from London and try to send their own message, but René catches on and tosses the radio out the window, which leaves the Resistance without a means to contact London, until Michelle thinks of the radio in Lieutenant Gruber's little tank.

Since Maria's disappearance, the café needs another waitress, but René and Edith has somewhat different ideas about who should fill the position, but finally Michelle from the Resistance brings tiny Mimi from another cell, to be René's bodyguard.

In the meantime, General von Klinkerhoffen gives the Colonel a new assistant, Italian liaison Bertorelli.

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.

Meanwhile, as Edith prepares for her wedding, René & Co. must get the aerial for their new radio above the jamming signal of Herr Flick, so they disguise Mimi as a small nun to obtain a box kite which they fly to contact London and request plastic explosive to blow up the safe in the General's chateau to get the British Invasion plans.

There is still no batteries for the wireless radio underneath the bed of René's mother in law, so Michelle's newest hairbrained scheme is to have René and Yvette powering the radio with the generator from a bicycle until the stolen batteries from a German midget submarine are delivered.

The Lieutenant is finished copying the paintings (The Fallen Madonna and the Van Gogh), and delivers them as sausages. Sausages also comes from Captain Bertorelli (real ones), Monsieur Leclerc (submarine batteries), and Officer Crabtree (explosives), and soon they're all mixed up in the German officers pants.

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.

Meanwhile, the British have sent a spy camera with which the Resistance should be able to photograph the plans for the German invasion of Great Britain, but the camera landed in the vineyard of Monsieur Alphonse's, and since the Germans commandeered the vineyard, the Resistance cannot go and look for the camera. This problem is solved when the General orders every peasant in Nouvion to work on the vineyard, which also leaves room for some assassination attempts on the General's life.

René is forced to masquerade as the head of the Gestapo, Heinrich Himmler himself, in an attempt to rescue Frau Von Kinkenrotten from prison. Of course, this is actually Herr Flick, still in his earlier disguise.

Armed with a camera disguised as a potato, René has to get into the chateau so he can photograph plans for the German invasion of Britain.

Leclerc and René plan to blow the safe in Lieutenant Gruber's bedroom. Edith's job is to drop a smoke canister down his chimney, but will she get the right one?

Having blown the safe in Lieutenant Gruber's bedroom, René and Leclerc are surprised by its contents. The Communist Resistance lies in wait for their escape, and holds them hostage in a sawmill.

Denise, the head of the Communist Resistance, who was René's sweetheart in his childhood in Nancy, and who's now determined to marry René.

Meanwhile, Edith and the servant girls have to explain to the Lieutenant why his little tank has crashed into the public toilet, and ends up getting Gruber's compassion.

René has a difficult time telling Edith that he will marry Denise, since Monsieur Alphonse has asked for Edith's hand, and Yvette has it in her heart to tell Edith that René will marry her instead.

René's friends rally round to try and save him from his impending marriage to the formidable leader of the Communist Resistance.

René and the Resistance need to find a huge amount of money quickly to save Mimi from the Communists.

When it is revealed that the one million francs stolen from the bank belong to Herr Flick of the Gestapo, the best place to hide them seems to be down René's trousers.

René has got rid of the Gestapo's money, next is the secret microfilm, but he is hampered by the Resistance girls in the cupboard.

While under interrogation, Alfonse's dicky ticker starts playing up, and he is whisked to hospital. He must be either rescued or eliminated before he can spill the beans about the stolen Gestapo money.

Michelle and Crabtree hatch another plot to get the British airmen back to Blighty. Captain Bertorelli has stolen Gestapo money planted on him.

Edith is in a romantic mood, and René is playing the piano.

Not only does René nearly get blown up by an exploding Christmas pudding, he also gets roped into another Resistance plan to smuggle out the British airmen.

René tries to sneak off to Switzerland with Yvette on the night train.

René attempts to sneak off to Switzerland with Yvette and four gold bars, but discovers the Resistance are intending to blow up their train.

Chaos engulfs René as he attempts to hide the stolen gold. Meanwhile, the Resistance plan to steal the Enigma encoder.

René asks Edith to marry him after hearing Monsieur Alphonse's intentions of asking for her hand in marriage. Meanwhile, General Von Klinkerhoffen suspects Colonel Von Strohm of stealing his gold, while Herr Flick suspects René.

René is still hiding the four bars of gold he has stolen and decides it is time he left his dangerous life in Nouvion.

René is still harbouring the German Enigma machine as well as the four bars of gold he has stolen, two British airmen and the painting of the Cracked Vase with the Big Daisies by Van Gogh. So the café is now full and getting more crowded by the minute.

The latest escape plan for the British airmen involves them wading along the canal underneath a tin bath. Herr Flick and Von Smallhausen pose as escaped British airmen, hoping to be picked up by the Resistance.

The Resistance have built a communication post in René's 'grave', in an effort to get around German jamming of their radio signals. René, Edith and Monsieur Alphonse try it out. René gets caught on the aerial and is hoisted above his 'grave'. Lieutenant Gruber sees him and thinks it's the ghost of René's 'twin brother'.
