The Blue Bonnet (1919)

As an infant, Ruth Drake was stolen from her father by her vengeful mother, and then abandoned. She was adopted and raised by a pawnbroker, and as a young woman joins the Salvation Army in order to help the kinds of people she has seen--and was--growing up. When war breaks out in Europe, she volunteers to go to France, and there meets a young man who has had an affair with a prominent actress. When Ruth and the man return to the US, the actress is outraged that her former boyfriend is now seeing Ruth, and sets up a scheme to frame Ruth for a robbery. However, during the trial certain facts come out that shock everyone.
