Blacula

Mamuwalde travels to Transylvania seeking Dracula's aid in stopping the slave trade. Dracula rejects him, insults his wife Luva, and bites Mamuwalde, transforming him into a vampire. Dracula curses him with the name Blacula and imprisons him in a sealed coffin beneath his castle while Luva dies in the chamber.

Blacula is placed in a sealed coffin in a crypt hidden beneath Dracula's castle. He remains trapped as Luva dies in the chamber, the fate of the two lovers sealed in darkness.

In 1972, Bobby McCoy and Billy Schaffer purchase the coffin and ship it to Los Angeles. They finally open the coffin, becoming Blacula's first victims and unleashing a string of murders that will plague the city.

Blacula spies on Tina at the funeral home and becomes obsessed, believing she is Luva reborn due to her resemblance. He trails her movements while she remains unaware of the lurking vampire. His fixation foreshadows the danger looming over Tina and her friends.

While pursuing Tina, Blacula is struck by a taxi, losing track of his quarry. He retaliates by killing the cab driver, Juanita Jones, and turning her into a vampire, adding another predator to the city.

At a nightclub celebrating Michelle's birthday, Blacula returns Tina's purse, drawing the attention of Tina and Detective Thomas who is investigating the earlier deaths. A call from the funeral director informs him that McCoy's body is missing, deepening the case.

Nancy, a photographer, takes a picture of Blacula with Tina, capturing evidence of his presence. Blacula murders Nancy and destroys the developed photo to prevent detection.

Thomas, Michelle, and Lt. Peters thaw Schaffer’s coffin, and the corpse rises as a vampire to attack Thomas. He battles back and drives a stake through Schaffer's heart, destroying the vampire.

Thomas arranges to thaw the body of Juanita Jones from the morgue to test a vampiric theory. The attendant Sam neglects to lock the door after a phone call, and Jones rises to attack Sam, the undead threat beginning in the morgue.

Thomas and Peters confront the undead Jones in the morgue. Thomas uses a cross to restrain her long enough to open the blinds and exposure to sunlight, destroying her.

Thomas searches Nancy's house and discovers a photo of Tina standing in front of an invisible Blacula, confirming Blacula as the vampire they seek and revealing Tina's complicity in the events.

Thomas hurries to Tina's apartment and confronts Blacula, but Blacula defeats him and escapes, taking Tina with him. A police officer is killed during the ensuing pursuit through the city streets.

Thomas, Peters, and the police track Blacula to a warehouse hideout where a nest of vampires, including McCoy, is destroyed. Blacula manages to slip away into the night, unresolved and dangerous.

Blacula hypnotizes Tina into following him to a nearby underground chemical plant hideout. He fends off officers, and a gunshot gravely wounds Tina, whom Blacula then turns into a vampire to save her life.

Peters stakes the newly turned Tina, believing Blacula will be found in the coffin. Devastated, Blacula climbs to the warehouse roof and, with the arrival of dawn, sacrifices himself as sunlight destroys him, his flesh melting away and leaving only bone.
