Lucy has cooked a special meal so that she and Lee can spend an evening in without distractions, talking about the state of their marriage. But Lee is obsessed with a beeping noise in the house that he can't find and the food is soon forgotten.

Brace for yuletide suburban chaos courtesy of Lee and Lucy as Lee throws everything at creating the perfect family Christmas, agreeing to Lucy's wishes to do something charitable and having "a normal Christmas where nothing goes wrong." This moment of festive spirit sees the couple invite Wilfred, a lonely pensioner from the nearby care home, to join them for Christmas dinner. The only instruction is that Wilfred is not, under any circumstances, allowed to drink alcohol…

Given best friends Toby and uptight ice-queen Anna are on hand, as well as Lucy's lovely mum Wendy with curmudgeonly dad Geoffrey, surely Lee can ensure this Christmas runs to plan?
