Dad's Army Season 3 Episode 10

Menace From the Deep

The platoon are assigned guard duty on an isolated, disused pier for a week. However thanks to Pike's poor judgment over what to tie the boat too, they end up stranded with no contact with the mainland and no food. Attempts at Morse code only prompt Hodges to pursue the platoon to get them to 'Put that light out!' and he ends up stranded himself. If that wasn't enough Jones spots a mine has floated under the pier, but does Hodges have a solution that'll 'bowl them over'?
