On a desolate beach near a lifesaving station, Ira, the youngest member of the lifeguard crew, rescues a baby girl from a wreck. The child is cared for at the station, where the men christen her Periwinkle. Living near the station are Ephraiam Rawlins and his childless daughter Ann, a widow with maternal longings. Joyously, Ann takes charge of Periwinkle and raises the girl as her own. Grown to adulthood, Periwinkle is the bright spot for the men at the station. One day, Richard Langdon Evans, a dissolute, wealthy young New Yorker, is cast ashore from the wreck of his yacht. Periwinkle, aiding the lifesavers, helps bring him back to life. Her innocent goodness and faith transform Dick from a carousing society ne'er-do-well to a man of noble ambitions. Thus rehabilitated, Dick wins Periwinkle's hand in marriage.
