Agnes is well-pleased with her state of the art remote-controlled Christmas tree - though less so with Buster's exploding crackers. She reluctantly agrees to help Mark and Betty by finding out what their son Bono wants from Santa before hosting the family's pre-Christmas party, which makes her very cross when nobody - especially Hillary - will play by the rules in her party games, as usual. Grandad's charades contribution turns out to be a mild heart attack but, after the guests have gone, he still has fun at Agnes's expense with the Christmas tree. Agnes resorts to desperate measures to discover what Bono wants from Santa - whose visit is not what she expected. However the whole family comes together for their Christmas Day musical finale.
