Papà dice messa (1996)

Father Arturo is a suburban parish priest, full of goodwill despite the absenteeism of his parishioners and the "harassment" from his bishop. One day, Francesco, the son he secretly had twenty years earlier, shows up at the church. His girlfriend, Matilda, is pregnant—Father Arturo is about to become a grandfather! The next day, Francesco disappears, and the priest and the girl set out to find him.
