When Fonzie has a very close shave in a stock car race, he begins to worry about his mortality and his soul. His friends, including Al are worried about him so Al suggests that he go along to see his brother, Father Anthony (also played by Al Molinaro) who is a Catholic priest.
Fonzie DOES go along to see the good father and is inspired by what he has to say, so inspired in fact that he decides that he wants to be Baptised. And so, the cast gather for Fonzie's reception into the Catholic Church.
There is nothing at all wrong with the premise of this episode but the script itself is very dull and boring and the performances from the cast aren't very inspiring either considering that it is a season finale. Let's hope for a better start to Season 5!
