Scream Blacula Scream

When the aging voodoo priestess Mama Loa dies, she has not selected who will be the next leader of her cult. Her ambitious and arrogant son, Willis Daniels, believes that he will be her successor, but the cult chooses his mother's adopted apprentice and his stepsister, Lisa Fortier, instead. Willis is angry and meets an old voodoo priest who sells him the bones of Mamuwalde, a.k.a. Blacula, and gives written instructions to him to seek revenge against the cult. He resurrects Mamuwalde, who turns him into a vampire and his minion. Mamuwalde goes to a party at Justin Carter's house and meets his girlfriend Lisa, who is now a powerful voodoo priestess. Mamuwalde continues his murder spree and, while Justin investigates the murder cases caused by him and his vampire minions, asks for help from Lisa to use her powers to free him of his vampire curse once and for all by using a voodoo doll.
