 Sister Bertrille meets Captain Otis Barnaby while he s working on his small boat, which he plans to sail to Miami. Captain Barnaby is as stereotypical an old seafaring captain as one could imagine. However looks can be deceiving. The stories he tells the sisters and the kids at the convent of his seafaring days are all tales of fancy as Otis Barnaby is no captain and is as much of a landlubber as one can be having lived his entire life in Lincoln Nebraska. Conrad, his son, wants Sister Bertrille to persuade Otis not to make the dangerous voyage. Nothing will dissuade him and he sets sail for Miami. A storm sets in and all at the convent are worried for his safety. He radios the convent. He is weak and without supplies - they went overboard - but his pride refuses to let them call in the Coast Gurad to rescue him. Armed with the necessary supplies, Sister Bertrille takes flight when the weather clears to find Otis at sea. She locates him. He thinks that she s a figment of his imagination. Once she sees that he s OK, she takes off once again to leave him to continue his voyage on his own. When Otis radios in to Conrad that he had a visit from "Sister Figment", Conrad promptly calls in the Coast Guard to save his obviously sick father. Sister Bertrille tries to convince Conrad to call off the Coast Guard, that his father isn t crazy, that Otis will finish his dream trip to Miami and that it really was her out at the boat. The statistician Conrad isn t convinced until Sister Bertrille gives him a flying demonstration. He ends up calling off the Coast Guard and Otis safely makes it to Miami.
