Per grazia ricevuta

A young man whose obsessive lifelong devotion to St. Eusebie has caused him to forego romance and a social life. After a sexual liaison with Delia Boccardo, he realizes what he's been missing in life and does a 180-degree turn into atheism! But when his Godless mentor Lionel Stander insists upon taking last rites when he dies, the befuddled Manfredi has no idea where he stands. (allmovie.com)
