When the wealthy count Waldemar Daninsky kills a wolf on his grounds, it transforms into a gypsy upon death, and he finds himself cursed by a vengeful gypsy witch who is angry about him killing one of her band. The witch orders a young, beautiful gypsy girl to seduce Daninsky and then, while he is sleeping, bite him with the skull of a wolf which she smuggles into the count's mansion. When she presses the skull's fangs into his skin, Waldemar becomes a werewolf (without a doubt the most original of all of Waldemar's various "origins" in the series).
