The film, a loose adaptation of the Edgar Allan Poe story "The Black Cat", tells the tale of a former vaudeville actor working with a mad scientist who attempts to bring life to the dead. The actor kills the doctor, and, in an effort to hide his crime, "becomes" the doctor, taking over his work, dressing like him, wearing his beard, and slowly going insane. The film features an actress named Phyllis Diller who is not the famous comedienne.
