On a dark and stormy evening, Alonzo Baldazon's jalopy of a car breaks down outside the convent where he takes refuge. The sisters provide him such, especially since they think he is down and out, however he is really a wealthy man, a fact which he doesn't tell them. The car is a vintage car which didn't run properly and the tattered clothes he was wearing are his car work clothes. Because he wants to repay the sisters for their generosity, he decides to take them up on their offer to be their handyman. He telephones his assistant Maurice back at his yacht to tell him his plans and to tell anyone who calls looking for him that he is in Canada on business. While at the convent, Alonzo not only does the odd jobs required but slowly finds out what needs replacing at the convent. One by one, large items miraculously end up at the convent - first a stove, then a hot water heater, then a children's wading pool - always after it seems like Sister Bertrille has wished for them. They first suspect Carlos as their benefactor, but when they find out he's not the generous soul, they think that Sister Bertrille is performing miracles. Finally just as he is ready to leave for good, Alonzo confesses he is the one providing the gifts. To prove such, he tells the Reverend Mother to phone his yacht, Maurice who tells her that the real Alonzo Baldazon is currently in Canada, as he was instructed to say. The Reverend Mother does not divulge this conversation to Alonzo before he leaves, but does so to the sisters after his departure. It isn't until Sister Bertrille takes a flight over the harbor and sees Alonzo on his yacht that she realizes that he was indeed telling the truth.
