When Catherine Hardwicke hires a young, unknown actor to play the lead in her new vampire movie "Twilight," Kristen Stewart is convinced from the start that something is not quite right about him.

What if the true identity of this man is not that of a young aspiring actor from London, but something completely different - an ancient Transylvanian vampire on the prowl for revenge and blood?
