Brendan O'Carroll returns as the daft-but-doting Irish matriarch for the first of two festive episodes - and as usual, there is mayhem in the Brown household. Grandad has got it into his head that the house is haunted, Rory hopes to improve his looks by undergoing plastic surgery and Cathy continues her search for the right man by getting herself an internet date. As for Agnes, her annual battles with the decorations may well be over as Buster has bought her a special tree. What could possibly go wrong?
