Wrongly imprisoned, Frederick Whithers is desperate to commit the crime he's already being punished for: defrauding the bank out of a vast inheritance. He fakes his death to escape, but when he's seen climbing out of a coffin everyone assumes he's a vampire; when he shows none of the traditional vampire weaknesses, they decide he must be the most powerful vampire in the history of the world.
