Very Confidential (1927)
Madge Murphy, a fashion model in a sporting goods store, learning that Adelaide Melbourne, "a famous sportswoman, is to spend the Summer in Alaska, conceives the idea of impersonating her at another resort in the hope of winning Roger Allen, who does not know, but greatly admires Miss Melbourne. She puts the deception over, but it involves her in a number of scrapes, trying to live up to her assumed reputation, including the handling of a speed boat and an auto race up a mountain trail, but she comes through triumphant and wins Roger in her proper person against the machinations of Priscilla Travers." - Moving Picture World.
