The Local Defence Volunteers have been renamed the Home Guard but they still have no uniforms and no weapons.
Captain Mainwaring still has plans to show Harry Hun what they will face if any of them show up in Walmington on Sea by teaching the men how to do unarmed combat. Corporal Jones faints when the breathing supply on his gas mask is cut off.
However crackpot Colonel Square shows up, a world war one veteran, who claims he can offer his men rifles, provided he gets to command the troops.
The men find out that Colonel Square still believes in the cavalry charge that went out with the ark. The men have to get on the horses and find out that they were trained for the circus.
It is interesting to see that Captain Mainwaring might be pompous but less of a buffoon in the early shows. The horse part was well staged.
