The Unfortunate Sex (1920)

Given away by her wealthy father, James Harrington, as an infant because she was born a female, Peggy has been raised by a kindly underworld crook. One day, while selling papers at the news stand, Peggy meets rising young attorney George Bentley who convinces her to aid the police in capturing Spike Kelly, a notorious member of her foster parent's gang. Peggy complies, and with her reward attends finishing school while Bentley tracks down her natural father who, having estranged his wife by his unnatural deed, is now remorseful. After reconciling husband, wife, and daughter, the young lawyer proposes to Peggy, assuring her that she should no longer consider herself a member of the unfortunate sex.
