[1][2][3] Molly O (Mary Pickford) is a poor little girl whose mother died in childbirth and father David King (Edward Martindel) rejects her.
When David departs to Italy to paint his dead wife as the Madonna, Molly O is left behind in a cruel orphanage.
She is beloved by the other pupils, but becomes enemies with the matron's niece Jennie (Mildred Morris).
As a result, she is shipped off to live with a boardinghouse proprietress (Maggie Weston).
Jennie pretends to be Molly O to make profit of his wealth and is adopted by him.
