In 1212, a Children's Crusade is launched after Jakob (John Fordyce) claims to have had a vision in which it is said that the innocence of children would be able to liberate Jerusalem. A monk (Lionel Stander), returning from Jerusalem, joins the crusade and hears the children's confessions, gradually realizing that most of them are not taking part for religious but more worldly reasons like rejected love.

Both Alexander (Mathieu Carrière) and Bianca (Pauline Challoner) are in love with Jakob. Alexander, who has learned that his adoptive father (and his lover), Count Ludwig (Ferdy Mayne), also a crusader, had killed Alexander's Greek parents, is gleeful that Jakob himself is in love with the Count, whom he had met after the Count and Alexander had split after an argument. This allows Alexander to take revenge for the Count's infidelity by telling his beloved Jakob about the Count's recent demise by drowning in a river, watched by an unmoved Alexander.

Finally, it is revealed in Jakob's confession that Jakob received the inspiration for the crusade not from God but from the Count, which means that the crusade must fail, since it is not by the will of God. However, the monk is unable to stop the children's progression and is left behind.
