On a small island in the Mediterranean Sea the usual representation of the nativity is in danger because the child that used to play Baby Jesus is now grown. On the island, a baby hasnt born since a long time and its necessary to find a new Baby Jesus. The mayor would like to borrow a child from the Tunisian community of the island, but between Italians and Tunisians there is bad blood. To help the mayor, there are Bilal, an Italian who converted to Islam and leads the Tunisian community, and Suor Marta, a nun who doesnt want to outrage the catholic tradition of the nativity.
