A mysterious Count Alucard arrives in America, claiming to be the nephew of Count Dracula. He quickly becomes involved with the wealthy Caldwell family, particularly the daughter, Claire, and her younger sister, Linda. As strange occurrences and deaths begin to plague the family, a professor who studies the occult suspects Alucard's true vampiric nature and attempts to uncover the truth.

Despite a somewhat convoluted plot, 'Son of Dracula' is often appreciated for its atmospheric direction by Robert Siodmak and Lon Chaney Jr.'s surprisingly nuanced performance as the titular vampire. It deviates from the typical Universal Monster formula, leaning more into a noirish, psychological horror. While not as iconic as its predecessors, it holds a significant place in the Universal horror canon for its unique take on the Dracula mythos.
