Description In the year 1506, the sorcerer Dr. Erasmus Craven (Vincent Price) has been mourning the death of his wife Lenore (Hazel Court) for over two years, much to the dismay of his daughter, Estelle (Olive Sturgess). One night he is visited by a raven, who happens to be a transformed wizard, Dr. Bedlo (Peter Lorre). Together they brew a potion that restores Bedlo to his old self. Bedlo explains that he had been transformed by the evil Dr. Scarabus (Boris Karloff) in an unfair duel, and both decide to see Scarabus, Bedlo to exact revenge and Craven to look for his wife's ghost, which Bedlo reportedly saw at Scarabus' castle. After fighting off an attack by Craven's coachman, who acted under the influence of Scarabus, they are joined by Craven's daughter Estelle and Bedlo's son Rexford (Jack Nicholson), and set out to the castle.
At the castle, Scarabus greets his guests with false friendship, and Bedlo is apparently killed as he conjures a storm in an act of defiance. At night, however, Rexford finds Bedlo alive and well, hiding in the castle. Craven, meanwhile, is visited and tormented by Lenore, who is revealed to be alive and well too, having faked her death two years before to become Scarabus' mistress. As Craven, Estelle, Rexford and Bedlo try to escape from the castle, Scarabus stops them, and they are imprisoned. Bedlo panics and begs Scarabus to turn him back into a raven rather than torture him. He then flees the dungeon by flying away. Craven is forced to choose between surrendering his magical secrets to Scarabus or watching his daughter be tortured. Bedlo secretly returns and frees Rexford, and together they aid Craven.
Craven and Scarabus sit facing each other, and engage in a magic duel. After a series of attacks, counterattacks and insults, during which Scarabus sets the castle on fire, Craven defeats Scarabus. Lenore tries to reconcile with him, claiming that she had been bewitched by Scarabus, but Craven rejects her. Craven, Bedlo, Estelle and Rexford escape just as the castle collapses on Scarabus and his mistress.
In the final scene, Bedlo, still a raven, tries to convince Craven to restore him to human form. Craven tells him to shut his beak, and says, to camera, "Quoth the raven – nevermore."
