Boy has always been relegated to the outskirts of his medieval village. With a hump on his back, a mysterious past, and a tendency to speak to animals, he is often made fun of. Everything changes upon the arrival of a shadowy pilgrim named Secundus. Impressed by Boy’s ability to climb and jump, he hires him as a servant and takes him on an action-filled journey throughout Europe in search of seven precious relics of Saint Peter. Boy soon realizes that they are stealing the relics and making dangerous enemies along the way. Boy is determined to see this pilgrimage to the end. Perhaps Saint Peter has the power to make him like everyone else.
