Ever since a certain Christmas Eve many years ago, Ebenezer Scrooge has become known all over London as the happiest, kindest and most generous of all men, always ready with a smile and a cheerful remark for his fellow begins, especially at the most festive time of year. But this Christmas Eve there is a blasphemous threat abroad in the city: corpses are rising from their graves and attacking people, spreading a deadly disease. As he, Bob Cratchit and their companions fight their way through the fogbound streets, their footsteps silenced by the blood- spattered snow, he realises that if they are goign to survive he will have to bury his nice and gentlemanly self, and learn how to be a black-hearted, mean-spirited scoundrel once more.
