The world's best vampire slayer (a comely young blonde) has been captured by the King of Vampires and languishes in his dungeons while her compatriots attempt to find a way in to release her. Meanwhile the King must somehow figure out how to stop the coming of a vampiric demon, who may end up making the world a hell on earth. The team-up between himself and his imprisoned enemy to stop this is inevitable, and surprisingly not so exciting.
