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 trying to impress Agnes by any means necessary. Meanwhile Dermot and Buster have organised this year's festivities at Foleys and are holding a murder mysteryystery night in aid of alcoholic greyhounds.

What could possibly go wrong?
