Dad's Army (1968)

S3E13 No Spring for Frazer

The hunt is on for a lost butterfly spring for Frazer's Lewis gun, which he misplaced during cleaning. The journey takes the group through Frazer's workshop, to a Funeral Director's place, and even to Mr. Bluett's dining room table, finally ending at a graveyard. Determined to retrieve the spring, the platoon engages in a series of audacious acts, including breaking and entering and grave robbing. But will their efforts be enough to recover it before Frazer faces a court martial?
