In medieval Europe aging Countess Elisabeth rules harshly with the help of lover Captain Dobi. Finding that washing in the blood of young girls makes her young again she gets Dobi to start abducting likely candidates. The Countess - pretending to be her own daughter - starts dallying with a younger man, much to Dobi's annoyance. The disappearances cause mounting terror locally, and when she finds out that only the blood of a virgin does the job, Dobi is sent out again with a more difficult task.
