Grissom and his team discover a young man strangled to death by hanging ...whose body looks like that of a woman. The boy's mother desperately wants answers to why her son is dead. (TV-PG)

At the request of Poppy (recurring guest star Alanis Morissette), Liz's new girlfriend, Liz gets surgery to improve her appearance. When James' (recurring guest star Jacqueline Bisset) life is threatened, she uses Christian to lure Michelle (recurring guest star Sanaa Lathan) into helping her steal another kidney within 24 hours. And Sean offers a surgical consultation to Marlowe (recurring guest star Peter Dinklage), who comes to McNamara/Troy hoping for a leg-lengthening procedure in order to impress the woman he loves. Recurring guest star Larry Hagman appears as Burt Landau.

Sean drinks to a great extent as he spends a depressing Christmas without his family; Christian gets an surprising gift when a 3-year old Wilber comes back into his life; and James pressures Michelle to help as she takes forceful measures to fill her holiday kidney quota.

Sean considers selling his shares of the practice to Christian and Michelle, although Michelle's past starts to threaten her future with Christian. Meanwhile, Escobar's wife needs cosmetic surgery.
