The Larkins have visitors they would rather avoid. There is tension between Mariette and Charley, and Alec Norman is up to his old dirty tricks.

In this festive special, the Larkins are gearing up for Christmas, and in the village all talk is of the pantomime and an ongoing spate of burglaries - with Miss Pilchester, the Normans and the local celebrity among the victims. While PC Harness applies his limited gifts to finding the culprit, Mariette and Charley take their love to the next level, and Pop and Ma are overjoyed to have the pair back for Christmas, but chaos descends when Charley's parents arrive to meet the Larkin clan, and the entire village is left without lighting and heating following a power cut.
