Dracula kills another innocent victim and Dr. Seward decides it's time to wipe him off the face of the earth. Armed with a hammer and a wooden stake, he arrives at Castle Dracula and duly dispatches the vampire Count. Next day, however, Dr. Frankenstein arrives with his assistant, Morpho, and a large crate containing the monster. Using the blood of a pub singer who has been abducted by his creation, the doctor brings Dracula back to life and uses him for his own ends. The Count and a female vampire continue to terrorise the town, so Dr Seward once again sets out for Castle Dracula. Unfortunately, he is attacked by the Frankenstein monster and left for dead. Amira, a gypsy, rescues him and summons up a werewolf to do battle with the forces of evil...
