Storyline

When a series of murders in the run-up to Christmas are found to be linked, FBI Special Agent Natalie Parker is tasked with tracking a pair of psychotic serial killers. But she soon discovers the couple are not only crazy, having met in and escaped from an asylum for the criminally insane, but have based their personas on Santa and Mrs Claus. As Christmas approaches, they slaughter their way through their special naughty list, playing a cat-and-mouse game with the FBI and leaving a trail of bloody bodies in their wake.
