The main player lives in the backcountry of Brazil, and the most valuable property is a donkey. When his donkey was seriously ill, he made a wish to God that as long as the donkey could recover, he would carry the cross like Jesus, all the way from his hometown to the provincial capital. Later, when the donkey really recovered, he went on his way to repay his wish. The problem is that when he finally gave the cross to the church, the priest listened to his reason and refused to accept it. The reason is that Sai should not have made such an oath. Sai refused to give up and waited outside the church. In this way, he became a news figure and alarmed the bishop. Despite the bishop's repeated persuasion, Sai refused to give up. He was killed in chaos when a riot was caused by the scandal of his wife's adultery. After Sai's death, his body was put on the cross and his wish was fulfilled. Although the film won the Cannes Award, it is still a neglected film. Some film history experts still give the film a very high historical status.
