Determination (1922)

London settlement worker John Morton, Jr., is unaware of the existence of his twin brother, James Melvale, a Paris man-about-town. Frances Lloyd, the wealthy daughter of an American senator, becomes interested in John's work and falls in love with him; but his rival, Lord Warburton, makes Frances believe that John is also James. After many adventures in the underworlds of London and Paris, Warburton is exposed as an impostor and leader of crooks; the brothers are reunited; James reforms; and John finds happiness with Frances.
