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 grew. Moreover, on the island a baby hasn't born since a long time and it's 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 doesn't want to outrage the catholic tradition of the nativity.
