It's Christmas in Finglas once again. Agnes has been recruited to the church choir, but she's under strict instructions from Father McBride that there's to be no singing and certainly no dancing. That's not the only thing off-limits: a Christmas tree shortage means Buster has to get even more creative than usual to impress Agnes. Meanwhile, Dermot and Buster have organised this year's festivities at Foleys and are holding a murder mystery night in aid of alcoholic greyhounds. What could possibly go wrong?

It's Christmas in Finglas once again, and this year Cathy has a new boyfriend, Boris. A last-minute change of plans leaves Agnes babysitting the widower's twins while he and Cathy head to Foley's for a quiet, romantic drink. Not everyone is convinced he's right for Cathy, and there are even suspicions that he might be a vampire. But it's not Boris that Agnes is worried about; she has her own concerns over his creepy twins.
