A Coast Guard crew recovers a six-year-old girl from a shipwreck and, nicknaming her Mermaid, brings her into their station, prompting practical and moral questions about care and community responsibility. Her presence rekindles long-standing tensions between Keeper John Smiley and his hard-edged sister Keturah, whose earlier antagonism contributed to the disappearance of John's young wife and child. The narrative follows the men’s efforts to clothe and house the girl, the town's gossip, and the quiet struggle of a man balancing duty, grief, and affection. Through episodes of rescue, domestic friction, and small-town observation, the work examines loyalty, jealousy, and fragile communal bonds.
