Accustomed to hosting his family's Christmas dinner, Frasier (Kelsey Grammer) objects to breaking tradition by having the festivities at the home of Niles (David Hyde Pierce) and Daphne (Jane Leeves). The ensuing quarrel prompts an angry Martin (John Mahoney) to bypass the dinner altogether and sign up for work on Christmas Eve. Suddenly contrite, Frasier and Niles do everything in their power to get their dad to change his mind. Elsewhere, Roz (Peri Gilpin) takes a liking to a personable department store Santa (Dean Cain). ~ Rovi
