Aged emissary Hitu arrives by Western sailing ship to the island of Bora Bora, a small island in the Oceania, on an important mission. He bears a message from the chief of Fanuma to the chief of Bora Bora: a maiden sacred to their gods has died, and Reri has been given the great honour of replacing her because of her royal blood and virtue. From this point on, she is tabu: "man must not touch her or cast upon her the eye of desire" upon penalty of death. This is painful news to Reri and the young man Matahi, who love each other. Matahi cannot bear it. That night, he sneaks her off the ship, and the couple escape the island by outrigger canoe.
