John and George McIntire are a couple of naive brothers who travel to a lawless western town to see their father. The bumbling siblings get themselves into big trouble after they beat up a member of a gang of extortionists. Fortunately, a mysterious roving gunfighter decides to help the guys out of their jam.
In 1212, a Children's Crusade is launched after a young shepherd, Jacques de Cloyes, claims to have had a vision in which it is said that the innocence of children would be able to liberate Jerusalem. A monk, returning from Holy Land, joins the crusade and hears the children's confessions, gradually realizing that most of them are taking part not for religious, but for more worldly reasons, like rejected love and hopes for freedom, the true nature of their enthusiasm is homosexual. In fact, if the children follow Jacques, it is more for romantic than religious reasons. They take literally the famous phrase: “Love one another”.
