1970s Brenitz, Stuttgart. As a spate of grisly murders spread throughout the town, the police think a serial killer is on the loose. However, the local coroner is sceptical. The truth is, something sinister is afoot. And with people dying left and right, a terrifying pattern dating back centuries emerges. As hair-raising similarities indicate the existence of an otherworldly force preying on the weak, the sudden arrival of mysterious Count Oblensky visiting his great-grandfather's castle further complicates matters. But the invisible killer is still out there, soaking the sleepy town in blood. If blood-thirsty vampires exist, who can stop the ancient menace?—Nick Riganas
People start getting murdered, and the coroner is convinced the killings are the workings of a reclusive odd baron who died decades ago. The baron's great grandson arrives to stay at his ancestor's castle as the strange murders continue.
