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.
