Sylvie Marley is a rare creature drawn to the Moon and the night with the urge to run wild in the bayous. She is also in love with the young, handsome werewolf Lucien Drago. She, too, could be a werewolf if she chose, called as she is by the spirit of the Moon and the family's werewolf curse. However, that choice may be taken from her by a madman seeking power as the new king of the Voodoos.
