 The bell at San Tanco is showing its age. Originally meant only to be temporary, the replacement bell sunk on the ship, the Hidalgo, off the coast of Puerto Rico when it was being shipped from Belgium 200 years prior. When Sister Bertrille can t fix the bell, she suggests looking for the wreck of the Hidalgo. She goes to the one person with the money and the boat to even attempt the location and salvage process: Carlos. Carlos agrees, but he really has other things on his mind. He is doing all of this in an attempt to woo his latest girlfriend, Binkie Worsley. He plans to plant a false treasure map, and buy a new bell for the convent, while taking Binkie out for a supposed sailing adventure to locate the wreck and the bell. His plans are thwarted when Sister Bertrille, with the Reverend Mother s reluctant blessing, insists on tagging along. But at least Carlos can still find his planted new bell and act the hero in front of Binkie, that is until Carlos s assistant, Pedro, spills wine on the map he drew with water soluble ink. Carlos dives again and again and again with no luck in finding the exact spot where Pedro planted the bell. Finally, Carlos finds the bell, just as Binkie goes overboard. They lose her. Sister Bertrille suggests she be the flying scout looking for Binkie from a hundred feet up. They find Binkie, on the most part all right. Carlos has become her savior and again plays the hero. However, Carlos  romantic plans are once again laid to rest as Binkie saw Sister Bertille flying while she was on death s edge out in the water, seeing it as a religious vision to change her ways. As for the bell, Pedro is having a hard time removing all the fake barnacles he placed on it because what they found was the real 200 year old bell.
