Mamluk is an unassuming, handsome young peasant who happens to have come along just in time to save the king from a fatal trap, and as a reward, the king offers him the amount of land he can mark off by walking around in one day but he must return to the starting point before sunset.

Caleb, "son of nobody" (Enrico Montesano) lives in Galilee in Jesus' day and struggles as a thief and con-man, pretending to be a magician. When he witnesses Jesus turning water into wine, he thinks he's found a competitor. So Caleb goes on, convinced that Jesus is a fake just as he is, always trying to figure out his tricks. In the meantime, he gets involved with a prostitute (played by Edwige Fenech), but also with the wife of a Roman patrician (played by the equally alluring Bernadette Lafont), he steals a few goats and cons a few people, he befriends a lovable dog and gets in trouble with some Roman soldiers.
