The Mass Is Ended (1985)

Young Father Giulio returns to Rome, where he was born and raised, to replace a priest who has left the clergy to start a family. He is delighted to reunite with his loved ones, especially his mother, sister, and old friends. Once radical leftists like Giulio himself, the latter are now each coping in their own way with the defeat of the revolution. Soon, however, Giulio realizes that despite his best efforts, he seems unable to solve the problems troubling those around him.
