The Girl from God's Country (1921)

J. Randall Carslake, a millionaire airplane manufacturer, his daughter, Marion, and her fiancé are on a hunting expedition in Canada. There they meet Neeka, a half-breed Native American, who rescues Carslake after her grandfather accuses the millionaire of betraying the girl's mother. Unaware that Neeka is actually his daughter, Carslake adopts the girl and takes her to California. Carslake is entered in a trans-Pacific flying race against Otto Kraus, who recruits Neeka as an ally after she and Marion quarrel over social blunders. Kraus obtains the secret of a "solidified gasoline," which Carslake himself has obtained fraudulently from a demented inventor. The inventor's consciousness returns during a hangar fire, and Neeka, realizing she has been duped, goes to his rescue. Carslake's pilot, Owen Glendon, is injured in fire, so Neeka volunteers the services of her sweetheart, blinded French aviator Pierre LeMort, for whom she will act as his eyes. Over the Pacific Ocean, Kraus attempts to ram the Carslake airplane, causing his own to crash. Neeka pursues the villain and he drowns during the ensuing fight.
