"Lark Pies to Cranchesterford" is a sunny costume spoof in which Victorian teenager Araminty Finch (Gina Bramhill) leaves her humble hamlet to work in the Post and Potato Office in the bustling town of Cranchesterford, where the local postmistress finds a love rival for the squire in a very camp postman. Also featured are a parody documentary in which soap actress Bo Beaumont (Dame Julie Walters), creator of the iconic Boadicea Overall in "Acorn Antics," tries to revive her flagging career by auditioning for reality shows, though it becomes apparent she has no talent; and coverage of the mid-life Olympics where medals are awarded for shopping and assembling flat-pack furniture. The finale sees Victoria perform her famous Ballad of Freda and Eric, accompanied by dozens of tap-dancing Freda and Eric look-alikes.
The Brockman family have decided to foster a sense of community by throwing a Christmas party for their neighbours (some of the guests dropped out because of a winter vomiting bug). Festivities do not go as smoothly as planned. Gran springs a surprise visit on the family, an unwell Jane shows up, whilst Jake seems to have fallen in with the wrong crowd. Karen would rather be playing online poker (illegally) than taking part in the celebrations, while Ben is enthusiastically left in charge of the party games, ranging from Swingball to blind football. As the party goes on, Pete gets locked in a bathroom with Jane, one guest's marriage falls apart and there is a visit by a police officer.
