When Jonathan Harker stays with Count Dracula in his crumbling Transylvanian castle, he is greatly unsettled by the man. After enduring a series of bizarre events, Harker realises he is being imprisoned by the Count and barely escapes with his life. Meanwhile, a similarly curious set of circumstances are happening in England: A huge wolf-like creature is seen to leap from the deck of a Russian ship with a mysteriously absent crew; a young woman develops a strange wasting disease and red marks on her throat; a patient at a lunatic asylum experiences increasingly strange delusions. A small band of heroes set to investigate these worrying events, led by Doctor Van Helsing who consults ancient texts to discover the chilling enormity of what they face.
