'Allo 'Allo!: De complete serie 4

Flick and Smallhausen dig another tunnel to the POW camp, Gruber gets access dressed as a nun. Meanwhile the POWs have concocted their own athletic method of getting over the barbed wire fence, with mixed results.

Flick realizes that everybody have escaped from the camp. He intercepts René's call to London which prompts René's panic reaction. Maria is marooned in Switzerland, and Geering - mistaken for a British officer - finds himself in London.

To replace Maria, Michelle introduces tiny but tenacious Mimi who becomes René's bodyguard and plans to poison Flick. Geering is replaced with womanizing Italian Captain Bertorelli who promptly collides with Mimi's ferocious nature.

Flick plants a microphone in Strohms office because he suspects a conspiracy. He also jams the radio signals of the resistance, so a larger aerial is needed. To this end Mimi, dressed as a nun, is airborne while attached to a box kite.

Michelle has René and Yvette pedaling a bicycle attached to a generator to power their secret wireless. Gruber delivers his forgeries of the paintings wrapped up in sausages which get mixed up with sausages containing explosives.

A British spy camera arrives because photographs of the German plans to invade England are needed. Two attempts to assassinate General von Klinkerhoffen involve poisoned wine and explosives hidden in Madame Fanny's wheelchair.
