The cafe staff, the Germans, and Michelle manage to escape thanks to the combined diversionary tactics of the camp entertainments and Gruber's refuse truck – but they find they have a couple of stowaways. Maria is not with them, having tried to escape through the post as a Red Cross parcel, but has been sent back to Switzerland due to insufficient postage. Captain Geering, having escaped over the wall, eventually manages to send a radio message – from London.

• Note: This episode is unique, in that it does not start with the standard theme tune, but instead with the music the gang are dancing to.
• Note: Although Sam Kelly does not physically appear in this episode, he has a handful of lines of audio dialogue as Geering.

Captain Geering is replaced by the Italian Captain Bertorelli. Maria is replaced, not by one of the many nubile young applicants for the post René favours, nor by the very elderly woman applicant Edith and Yvette favour, but by Mimi Labonq, a Resistance fighter and former gang leader, under Michelle's orders.

• Note: In the office, Captain Bertorelli tells General von Klinkerhoffen that he has a medal for fighting in Abyssinia. Ethiopia was generally known as Abyssinia in Europe until the mid-twentieth century. It was occupied by Italy from 1936 until 1941.
• Note: This episode features the first appearance of Sue Hodge as Mimi Labonq.
• Note: This episode features the first appearance of Gavin Richards as Captain Alberto Bertorelli.

Herr Flick decides to bug the Colonel's office – with a daffodil. The Resistance must take action as their radio signal is being jammed by the Gestapo, which leads to Mimi hanging off the line of a kite while disguised as a nun.

Without batteries to power the radio in the attic bedroom, René and Yvette must provide pedal power attached to a generator. René amasses a collection of sausages – some real, one containing a forged painting, and some containing explosives.

• Note: Even though René is the third person to appear in this episode, Gorden Kaye is first in the "cast in order of appearance" list at the end of it.

General Von Klinkerhoffen has commandeered Monsieur Alfonse's vineyard and the locals are ordered to harvest the grapes. The RAF has dropped a spy camera, which has landed in the vineyard. The Resistance decide that the harvesting is the ideal opportunity to rescue the camera, and to assassinate the General.
