This bargain-basement sequel is unusual in that it completely contradicts the conclusions drawn by its predecessor, Bela Lugosi's 1941 horror film The Devil Bat. It all begins with Nina, the daughter of the notorious Dr. Paul Carruthers, the crazed, vengeful scientist who allegedly created a species of giant killer bats that would attack and kill anyone wearing a certain scent. Nina has been plagued with terrifying recurring nightmares featuring giant bats. Thinking she, like her father, may have more than a few in her belfry, Nina goes to see a psychiatrist who uses her psychosis for his own evil ends by framing her for the murder of his wife. Fortunately, by the story's end she not only proves her own innocence, she also clears her father's name and proves that he was really just misunderstood.
