Dracula's ring (1978)

Three young Danes are vacationing in Malta. In the basement of an old castle ruin, they find a finger ring and a stone sarcophagus, and accidentally loosen the chains that have sealed the sarcophagus. Count Dracula awakens in the coffin—and he wants his ring back! The vampire count follows the three tourists back to Denmark, leading to dramatic encounters in Copenhagen and Aalborg, and the series ends with a dramatic confrontation in Aarhus.
