Dracula: Prince of Darkness

Ten year after the events in Horror of Dracula (1958), brothers Charles and Alan Kent and their wives Diana and Helen are holidaying in the Carpathians. A traveling monk, Father Sandor, warns them to avoid the nearby castle at all costs which would have been easy since it can't be located on a map and the locals profess no knowledge of a castle nearby. When their coach driver abandons them in a forest due to impending darkness they see the castle in the distance. They enter and find it well maintained and in fact the only person there is Klove, who said his late master left instructions that all travelers seeking refuge were to be given a meal and a place to sleep. Unbeknown to the travelers Klove serves Count Dracula and the blood of one them is used to resurrect him. Charles and Diana escape and seek the assistance of Father Sandor. Before they can send Diana to safety in England, Dracula kidnaps her forcing Charles and Father Sandor to follow Dracula to his own castle and hunt him down.
