O'Carroll himself plays his drag persona, Agnes Brown, with several close friends and family members making up the rest of the cast.
Dermot's soon-to-be mother-in-law, Mrs. Hillary Nicholson visits; upon seeing the Browns, she thinks they're white trash and relocates the wedding to Italy.
Buster involves Dermot in a raffle scam that ends up saving the day when Winnie's husband Jacko needs €5,000 for an operation.
After hearing that Mrs. Nicholson has two toilets, Agnes has a second one installed under the stairs to impress her, but Grandad answers a call of nature in the wrong cupboard.
Agnes has a new Christmas tree courtesy of Buster, which turns out to be an automatic side brusher that he stole from the local car wash.
Meanwhile, Rory has had plastic surgery to improve his looks and spends most of this episode with his head bandaged, Dermot and Buster run a Santa's Grotto, with Grandad as Father Christmas and Bono as an elf--until Betty finds he's been missing school; Grandad thinks the house is haunted after watching a horror movie; Cathy has a new Internet boyfriend, Jake.
