Mary Fenton, the star singer in her small town church choir, is assured by a phony impresario that with six months of voice lessons at his New York school, she will become famous. When the hopeful young girl arrives in New York, she finds the school closed, and is soon robbed of all her money. Sitting on a park bench, broke and friendless, she attracts the attention of Charles Owen, who lures her to his apartment with promises of money and protection. When his wife's friend drops by the apartment, Charles introduces Mary as his wealthy sister-in-law, and soon she is invited to visit the country home of his friends, the Walfords. After Owen's wife returns, Mary is forced to confess everything to the Walfords, but young Blake Walford, who has fallen in love with her, forgives her and proposes.

Penniless, half-starved, and unfamiliar with the big town, Mary Fenton asks Charles Owen for aid. He thinks it something of a lark to take the innocent, confiding girl to his hotel for something to eat and a chance to get warm, but he is discovered by friends in what might have been a compromising situation and to pass it off he introduces Mary as his wife's sister. She is made much of by his circle of acquaintances until Mrs. Owen returns and then Mary takes the only way out, frank confession and is an impostor no longer.—Moving Picture World synopsis
