Marcy McKay, despite her love for the harbor section of Clifton, Michigan, feels a vague yearning to become part of the rich section of town, that private and elegant world which exists a hundred steps above her waterfront home. In her junior year at high school, her beauty and her liveliness win her a peripheral place in this coveted world. Delighted, she nevertheless finds it difficult to accept the snobbery and vandalism of her spoilt and rich friends, a vandalism which nearly involves her in a serious brush with the law. When her father, a ship captain, is threatened by a storm over Lake Superior, Marcy realizes her sincere feelings for her own way of life, and turning with love to Bill, a neighbor, whose bravery and integrity distinguish him from her playboy companions, she finally accepts herself and the world into which she has been born. A light and pleasant variation on that old, old theme of rich little poor girl.
