Jane Cogden and her sister Lucy live together. Jane has two admirers, John Cavendish, the village doctor, and Bart Holt, son of an old sea captain. Jane fails to respond to Bart's attentions and he turns to Lucy. These two become separated from the others while on a sailing party and are marooned on an island. When they return in the morning Bart is met with the news that he must sail on a three months' cruise. Lucy, on hearing this, becomes frightened and tells her sister the story. Jane the next day goes to demand at once of Bart's father the marriage of Lucy and Bart. She finds the old man heartbroken by the news of the death of his son at sea. Jane takes Lucy to Paris, keeping her ignorant of the death of Bart, and here she proves to be the same as before, frivolous and thoughtless. One day Sydney Gray, an old friend of John Cavendish, calls on the girls. Lucy tells him that the child which Jane is forced to take care of belongs to Jane through secret marriage. Not long after, Jane receives a visit from Lucy and Sydney, now her husband. Jane demands that Lucy make known the facts concerning the child, whom she has taken back to America with her, to Sydney at once. She promises to do so the next morning. On the following day little Archie, while playing in a boat, is caught in the tide and carried out to sea. He is rescued by Jane's old admirer, who nearly loses his life in the attempt. Carried to shore by an old sea captain, the little fellow is revived, and here Bart's father reveals the identity of the child, accusing Lucy of being the mother. Through the pleading of Jane, Lucy is forgiven by Sydney and Jane goes to John, who is waiting for her.
