Don Camillo e i giovani d'oggi (1972)

Embattled priest Don Camillo faces his biggest challenge yet: modernity. First, his ecclesiastical superiors send him a hip young curate (Don Chichí) with a mandate to bring Vatican II to his rural parish. Then he receives a visit from his wayward niece "Cat," a flower child determined to turn the Little World upside down. Meanwhile, Don Camillo's old adversary, communist Mayor Peppone, must deal with his own grown son, a rebel in search of a cause.
