The power haunted island off Maine, Landfall, is the domain of John Fordyee who has made serfs of the villagers, an invalid of his wife and enemies of his sons, Oliver and Ross. With their mother's death, they become more rebellious when Mr. Johnny brings back a new bride, Christine, who wins their love and with whom Ross cuckolds his father. The suicide of the school teacher reveals another of Mr. Johnny's bastards; the Grahams' purchase of Parnassus, another island Mr. Johnny had intended for his, sets off bloody violence; Christine's efforts to persuade her husband to let the villagers live away from the harbor are only partly successful when he limits his permissions; Ross pursues his plans for killing his father. He is successful in preventing another attack on the Grahams, watches the village, united, defy Mr. Johnny and threaten to abandon Landfall and sees his death-wish come true without being guilty of the deep. He finds he has no part in Christine's future and recognizes the bonds that hold him to the island are unbreakable. A guilt ridden feudal lord is a thorough-going explain and makes a wily opponent for his young adversary in a drama that is colored by island life and played out by salty villagers.
