After Helen's husband dies, her father John Thorpe, who had always disapproved of the marriage, puts her young daughter in an orphanage and tells Helen that the girl has died. Fifteen years later, the girl, Faith, becomes a servant in John's house, but neither she nor the old man know of their relationship. Meanwhile, John's young stepdaughter Laura becomes pregnant, but her boyfriend refuses to marry her. To pay for an abortion, Laura steals money from John and persuades Faith to take the blame. In court, however, lawyer Mark Strong proves that Faith is innocent, and also reveals the real story of her past, thereby reuniting her with her mother.
