Synopsis by Hal Erickson
The third of director Marshall Neilan's nine 1917 releases, The Tides of Barnegat, starred Neilan's future wife Blanche Sweet as Jane Cogden. For the sake of her younger sister Lucy (Norma Nicholas, Jane sacrifices her own happiness, even unto waiting on little Lucy hand and foot. When Lucy's reckless romance with a sailor results in an out-of-wedlock pregnancy, Jane spends her meager savings on a trip to Europe for herself and Lucy, so that her sister can give birth to the baby far from the prying eyes of the local gossips. And once the child is born, Jane takes it upon herself to care for the baby, leaving Lucy free to marry her new sweetheart Sydney Grey (played by the "original" Harrison Ford). Upon her return home, Jane is presumed to be the mother of the child, and as a result both she and the baby are shunned by the community. Eventually, Lucy's conscience gets the better of her and she blurts out the truth. Absolved of all guilt, Jane at last feels worthy enough to marry Dr. John Cavendish (Elliot Dexter), who has loved her all along despite her "shame."
