Arriving in wind-swept San Juan to enter the Convent San Tanco, Sister Bertrille , a novice from the U.S., discovers that she can fly. Before Sister Jacqueline and Sister Sixto reach the pier to welcome her, Sister Bertrille is blown into the sea. She swims to the yacht of Carlos Ramirez, a wealthy discotheque owner and unwittingly spoils Carlos' plans for a fun-filled weekend. At the convent, again lifted by the wind, Sister Bertrille concludes that her flying is a quirk of aerodynamics controlled by the tilt of her cornette. Appalled by the shabbiness of the children and lack of space and equipment, Sister Bertrille starts a campaign to raise money. Mother Superior, who has been fighting poverty for years, is outraged when she finds the nuns selling cookies, paintings, and straw hats, putting on a show in the town square. Sister Bertrille learns that Carlos owns a piece of land the sisters need but can't persuade him to donate it to them. When the wind carries her off again, Sister Bertrille stuns a submarine crew by landing on their surfaced craft. Carlos, en route to a rendezvous with Louise, sees Sister Bertrille flying near his plane. Feeling he has had a religious experience, he turns back and donates his land to the convent. Sister Bertrille crashes into an Army base and is held as a spy. She is released when Mother Superior and Sister Jacqueline vouch for her and Carlos testifies he saw her flying. Sister Bertrille sews weights in her habit to keep her grounded and turns down an offer to appear on the Ed Sullivan show.

Angry, Darrin storms out. Endora compliments Serena on a fine job. Darrin returns to find Serena ready to go out in a miniskirt. She answers his protests by changing herself into a slattern. When Abner, returning the sugar, reports Gladys saw Samantha at the bazaar, Darrin gets a glimmer, but thinks it was Samantha's double. As Samantha enters with a large pie, Darrin, thinking she is the double, shoves it in her face. Samantha, protesting her innocence, twitches up another pie. As Darrin grabs it, Samantha ducks and Endora gets the pie instead. When Serena appears, Darrin realizes his mistake. Later, Samantha reports that Endora, after a trial, is serving out her punishment. As Endora skywrites "I promise never to bother 'What's-his Name' again," Samantha knows her mother has had the last word.

The Convent San Tanco suffers through a heat wave. Then Sister Bertrille arrives with air conditioners, wangled from Carlos Ramirez, when he installed new ones in his casino.
