After Jonathan Harker attacks Dracula at his castle (apparently somewhere in Germany), the vampire travels to a nearby city, where he preys on the family of Harker's fiancée. The only one who may be able to protect them is Dr. van Helsing, Harker's friend and fellow-student of vampires, who is determined to destroy Dracula, whatever the cost.

This is the true story of Oberleutnant Franz von Werra, the only German prisoner of war to escape from imprisonment in Britain during the Second World War.
