René Artois, owner of the Café René in the French village of Nouvion, is 'persuaded' by the Resistance to hide two escaping British airmen. René is more interested in having affairs with his two waitresses without his wife finding out.

The Germans, who are occupying the village, are busy looting anything valuable.

The airmen's escape is thwarted by Nazi gunfire, and the air balloon crashes into Madame Fanny's bedroom.

General Von Klinkerhoffen takes command of Nouvion and orders Colonel Von Strohm to woo Edith in order to infiltrate the Résistance. The Colonel soon relegates the duty to Captain Hans Geering. Herr Flick plots the death of the General by poisoned dart, with Helga assigned to do the fatal deed. The Colonel and the Captain plan to poison the General's wine with a lethal pill, whilst Michelle has Edith make a Black Forest Gateau packed with dynamite.

Two years have passed. The airmen have finally escaped to England and Captain Bertorelli and his Italian troops have gone home. René thinks life is now relatively peaceful. Then Yvette announces that she's pregnant.

Colonel Von Strohm and Lieutenant Gruber get Helga to steal the painting of the 'Fallen Madonna' from Herr Flick. She cuts off one of the boobies and keeps it, to make sure that she'll get her 'cut' when the painting is sold.

René and Edith are in the Alps celebrating Edith's birthday. As they drink champagne and eat cake they start to reminisce about the WWII days, and we are shown several clips with highlights from the entire series. Some of the clips include: Michelle's many "I shall say this only once" plans, René's shooting, the flying nun, Crabtree's bad french, Gruber's advances towards René, René's affairs with the girls, Fanny and Leclerc in the foldup-bed, Leclerc's disguises etc.
