The story in one page
When a gargantuan helmet falls from the sky and flattens his son on his wedding day, Manfred panics — not about the burial, but the loss of his dynasty. He decides to divorce his wife, Hippolita, and marry the intended bride, Isabella, himself. Isabella flees into the castle's labyrinthine vaults with the help of a young peasant named Theodore. Supernatural architecture begins to protest: portraits sigh, statues bleed, and colossal limbs haunt the corridors. After a series of dramatic revealings and tragic accidents, Manfred's claim to the throne disintegrates. Theodore is unmasked as the true heir, Manfred retreats to a monastery, and the castle finally stops vibrating.
