In a harbour town long ago, a boy is entranced by his uncle's stories of adventure in lands far away. Ignoring the crazy talk of the harbour pilot's son about the uncle being the Devil, the boy boards a ship with his uncle. But the uncle soon makes enemies of the captain and crew and, in frustration at their superstition, kills an albatross that has befriended the ship. As the ship sails on, madness and death ensue, and the boy and the crew face unimaginable horrors.
