 Marcilla Karnstein from time to time comes back from her death sleep, and under a different name, such as Carmilla or, now, Mircalla, spreads terror in a village with her vampire powers. General Von Spielsdorf loses his nubile daughter to Mircalla, and swears revenge, with the help of expert vampire-killer Baron Hartog, and the Doctor. Eventually, they will kill the female vampire, but not before she traps a number of female lovers/victims.
