Amid the harsh brutality of the times, an unlikely hope emerges in the form of a young shepherd named Etienne, who has a vision to lead children on a different kind of crusade-one founded on peace rather then violence.
Etienne, acting on a vision of St. Nicholas, joins with two other young people, Abel and Blanche, to lead a crusade of children of different faiths to Jerusalem in 1212, at the height of the religious wars.
