Dracula: Prince of Darkness

While holidaying in the Carpathian Mountains, two couples inadvertently discover the ruins of Count Dracula's castle. In a sinister turn, the Count's loyal servant murders one of the men and hangs his body over Dracula's ashes, allowing blood to seep into the remains. This dark ritual successfully resurrects the Count, who immediately fixates on the slain man's wife, aiming to draw her into a world of darkness and moral corruption as his new companion.
