The Secret Sin

Blanche Sweet has a dual role in this picture -- she plays twin sisters, Edith, a sweet, normal young girl, and Grace, who is a drug fiend. They live in poverty with their parents and their father (Hal Clements) finally finds work. Because he is faithful to his boss (Thomas Meighan), he is offered a partnership.
