"Son of Dracula" (1943) A Universal Horror Photoplay

☆Count Alucard is invited by Katherine Caldwell to the United States. Caldwell is one of the daughters of New Orleans plantation owner Colonel Caldwell. Shortly after his arrival, the Colonel dies of apparent heart failure and leaves his wealth to his two daughters. Claire receives all his money and Katherine his estate "Dark Oaks". Katherine has been secretly seeing Alucard and the two are quickly married. Her former long-time fiancé Frank Stanley confronts the couple and tries to shoot Alucard. The bullets pass through the Count's body and hit Katherine. Assuming she is dead, a shocked Frank runs off to tell Dr. Brewster what has happened. On the doctor's arrival, he is greeted by Alucard and a living Katherine. The couple instruct him that they will be devoting their days to scientific research and only welcome visitors at night. Frank goes on to the police and confesses to the murder of Katherine. Brewster tries to convince the Sheriff that he saw Katherine alive, but the Sheriff insists on searching Dark Oaks. He finds Katherine's dead body and has her transferred to the morgue. Frank is charged with murder and put in jail.
☆Meanwhile, Hungarian Professor Lazlo arrives at Brewster's house. Brewster has noticed that Alucard is Dracula spelled backwards and Lazlo suspects vampirism and says the Alucard could be a descendent of Count Dracula himself. While they are talking Alucard appears and tries to attack Dr. Brewster but Professor Lazlo drives him away with a cross. A local boy brought to Brewster's house confirms this suspicion—there are bite marks on his neck. Katherine sneaks into Frank's cell and explains that she only married Alucard to obtain immortality and wants to share it with Frank, her true love. He is initially repulsed by her idea, but then yields to her. After she explains that she has already drunk some of his blood, she advises him on how to destroy Alucard. He breaks out of prison, seeks out Alucard's hiding place and burns his coffin. Without his daytime sanctuary, Alucard is destroyed when the sun rises. Brewster, Lazlo, and the Sheriff arrive at the scene to find Alucard's remains.
☆Meanwhile, Frank stumbles into the playroom where Katherine said she would be. He finds her coffin and gazes down at her lifeless body. Knowing he must kill the love of his life, Frank takes off his ring and puts it on Katherine's left ring finger. Once Brewster and the others reach the room, they see Frank appear at the door. He steps back allowing them to follow. As they enter the room, they see Katherine's burning coffin. They all stare, speechlessly, while Frank mourns the loss of his love.
