Gaspard, a teenager from the suburbs of Lisbon, falls into the hands of the Ogre, a man who has made a pact with the Devil. The Ogre uses the boy to attract tourists, whom he transforms into animals and then kills. Gaspard escapes with a donkey and a dog that he has grown fond of, and in an enchanted manor, he meets the spirit of Queen D. Maria I. Meanwhile, enraged, the Ogre sets off in pursuit.
