context: In 1780, Prince Mamuwalde (William Marshall), the ruler of the Abani African nation, seeks the help of Count Dracula (Charles Macaulay) in suppressing the slave trade. Dracula refuses to help, and transforms Mamuwalde into a vampire, whom he names Blacula and imprisons in a sealed coffin. Mamuwalde's wife, Luva (Vonetta McGee), is also imprisoned and dies in captivity. In 1972, the coffin has been purchased as part of an estate by two interior decorators, Bobby McCoy (Ted Harris) and Billy Schaffer (Rick Metzler) and shipped to Los Angeles. Bobby and Billy open the coffin and become Prince Mamuwalde's first victims. At the funeral home where Bobby McCoy's body is laid, Mamuwalde spies on mourning friends Tina Williams (Vonetta McGee), her sister Michelle (Denise Nicholas), and Michelle's boyfriend, Dr. Gordon Thomas (Thalmus Rasulala), a pathologist for the Los Angeles Police Department. Mamuwalde believes Tina is the reincarnation of his deceased wife, Luva. On close investigation of the corpse at the funeral home, Dr. Thomas notices oddities with Bobby McCoy's death that he later concludes to be consistent with vampire folklore.
  Prince Mamuwalde continues to kill and transform various people he encounters, as Tina begins to fall in love with him. Thomas, his colleague Lt. Peters (Gordon Pinsent), and Michelle follow the trail of murder victims and begin to believe a vampire is responsible. After Thomas digs up Billy's coffin, Billy's corpse rises as a vampire and attacks Thomas, who fends him off and drives a stake through his heart. After finding a photo taken of Mamuwalde and Tina in which Mamuwalde's body is not visible, Thomas and Peters track Mamuwalde to his hideout, the warehouse where Bobby McCoy and Billy Schaffer were first slain. They defeat several vampires, but Mamuwalde manages to escape. Later, Mamuwalde lures Tina to his new hideout at the nearby waterworks plant, while Thomas and a group of police officers pursue him. Mamuwalde dispatches several officers, but one of them manages to shoot Tina. To save Tina from death, Mamuwalde transforms her into a vampire. After Peters manages to kill the vampire Tina, Mamuwalde believes he cannot live any longer after losing her twice. Mamuwalde leaves for the surface where the morning sunlight rots his flesh quickly and kills him.
