A young, beautiful prostitute named Sadie Thompson arrives on the South Pacific island of Pago Pago looking for honest work and falls for Timothy O'Hara, an American sailor who is unfazed by her unsavory past. However, Mr. Davidson, a missionary who arrived on the island at the same time, aims to "save" Sadie from her sinful life and petitions to have her separated from her beau and deported back to San Francisco.
