Set in the 1920s in Pago Pago, Eastern Samoa, Charlotte, an American painter, arrives from Boston on the island of Alaya to visit her father, U. S. Navy Captain Bruckner, whom she hasn't seen in quite some time. Bruckner is the U.S. Congress-sanctioned Governor of the island, and he rules it with a stern, patrician, and thoroughly patronizing attitude towards the natives. Charlotte is somewhat taken aback by her father's rigid adherence to the law, particularly when she tries to intervene on behalf of Bruckner's charge/houseboy Matangi, who has involved Charlotte in a scheme to get Bruckner to toss out a harsh penalty issued to a native man who stole a boat "for love." Bruckner refuses, pish-poshing all this talk of love over the law, and severely reprimands Matangi, much to Charlotte's dismay.

From July to December every year, the Caribbean crawls with these evil offspring of the elements..."
