When a measles epidemic temporarily prevents the Davidsons and the Macphails from continuing their journey to Apia, Western Samoa, they find themselves stranded in Pago-Pago. Though the two couples have socialized on shipboard, they are very different: The Davidsons, who have been absent from their medical and religious mission north of Samoa for a year, are religious zealots whose single aim in life is to convert Samoans to Christianity. They are a drab and humorless pair who associate with the Macphails only because the rest of the ship’s passengers seem “fast” by comparison. Though the women find much to talk about, the men share only an association with medicine, for Dr. Macphail is a shy, contemplative man to whom religion means little.
When it is announced that they will be unable to leave the island for at least ten days, the energetic Davidsons take action. Through his influence with the governor, Davidson is able to find them rooms in the establishment of Mr. Horn, a local trader. Mrs. Davidson, with characteristic efficiency, helps the rather ineffectual Macphails settle into the boardinghouse, determined to make the best of things in spite of the bleak environment.
Soon Macphail learns that another of their shipmates will be lodging at Horn’s, a second-class passenger named Sadie Thompson. Sadie, en route to Apia where a job supposedly awaits her, has been judged “fast” by Mrs. Davidson and Mrs. Macphail for dancing with the ship’s quartermaster at the shipboard party the night before the landing at Pago-Pago. Vulgar in appearance and speech, Sadie is a friendly and vivacious sort who seeks, in the ensuing days, to enliven the depressing boardinghouse by giving frequent parties, loud and raucous affairs attended solely by the island’s sailors. One evening the couples’ dinner conversation is interrupted by especially loud noises coming from Sadie’s room on the floor below. As they try to talk over the din, Davidson has a sudden revelation: Sadie, who boarded the ship at Honolulu, must be a denizen of Iwelei, that city’s notorious red-light district, which has only recently been shut down through the efforts of Hawaiian missionaries. Further, she must be plying her trade here in Pago-Pago—just below them in her room at Horn’s.
Over the objections of Macphail, who considers Sadie’s actions none of their business, Davidson insists on storming into her room and trying to break up the party. As his wife and the Macphails listen, Davidson is thrown out of the room by the sailors. After the Davidsons go to their room, the party starts up again, even louder than before.
The arrival of the ship in Pago-Pago has coincided with the beginning of the tropical rainy season, and rain falls almost ceaselessly during the time period covered by the story—torrential, oppressive rain, which depresses the Macphails and greatly adds...
