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.

Fatma 75 is a pioneering film: it is the first non-fiction film by a Tunisian woman, a feminist essay-film, and the first in a series of powerful films about strong female figures in the country. The film was made in the UN International Women's Year, 1975, and has long been recognised as one of the most important films from North Africa.
