After Jones mistakenly shoots a turkey on patrol and its owner cannot be found, the platoon decides to hold a turkey dinner and treat the town's senior citizens.

Lady Maltby donates her Rolls-Royce for use as a staff car. Wilson and Pike are assigned to paint it for camouflage, but instead they mistakenly paint the Mayor's Rolls-Royce, just before a French general is due to visit the town.

The platoon dresses up as morris dancers as part of a carnival to raise money for the town's Spitfire fund, which is still £2,000 short. A Lady Godiva figure will lead the parade but there is confusion over who this will be.

On a field exercise acting as commandos meeting a secret agent (represented by Mainwaring), the platoon must trust no one for GHQ has sent out counter agents to catch them. The appearance of a gorilla compounds their problem.

A landmine has destroyed 100 yards (92 m) of railway track, along with the water and gas mains, and the telephone line. Compounding the problem, Pike gets his head stuck between the bars of a gate. Mainwaring declares martial law.

The platoon is given the job of signposting the area for an Army exercise, but a steam engine is blocking the route. When Jones tries to drive round it, his van becomes stuck, blocking both Hodges in his van and Mr Farthing with his bus of pensioners.
