After his impetuous musician girlfriend, Samantha, dies in an accident shortly after they had a fight (and nearly broke up), a grief-stricken British businessman, Ian Wyndham, living in London gets a chance to relive the day all over again, in the hope of changing the events that led up to her getting killed.

Mark 13 is a government-built killing machine programmed with artificial intelligence, able to repair and recharge itself from any energy source. Through a series of coincidences, the cyborg's head ends up in the home of a sculptress as a bizarre Christmas present from her boyfriend. Once inside its new home, the cyborg promptly reconstructs the rest of its body using a variety of household utensils and proceeds to go on a murderous rampage.
