The Understudy (1917)

Stage-struck Georgianna Lane leaves her country home for the bright lights of the city. Once there, however, she fails miserably and contemplates suicide. Meanwhile, Hope Van Alen, the wife of wealthy Anthony Van Alen, is suffering from drug addiction and decides to enter Dr. Pope's sanitarium for a cure. Coincidence brings the couple into contact with Georgianna, who bears a striking resemblance to Hope. To deceive their friends in Hope's absence, the Van Alens enlist Georgianna's acting abilities in impersonating Hope. The switch is made and Georgianna performs so well that Anthony's nephew Gerald Fownes finds himself falling in love with her. When the real hope suddenly returns, cured, Gerald is bewildered. Explanations are made and Gerald joins Georgianna, who has contentedly returned to her country home.
