Both the light and dark sides of Will's character come to the fore on a Christmas Eve. Will has fallen to the seductive charms of a stripper/prostitute and is prepared to spend part of the holiday with her. But in acting as a physician to humans, Will has sometimes been called into real human medical service. Choosing to live amongst humans proves challenging, especially when confronted with those on the verge of death.

On this holiest of eves, he comes across a horrible accident and must come to the aid of its victims. But he hasn't fed for a while and is tested to incredible limits of vampire restraint. Will he be able to help the victims without feeding? Or will he succumb to a blood lust before seeing his lady of the evening? Could Christmas be any more interesting?
