In Old Kentucky (film 1919)

Illiterate Blue Ridge Mountain girl Madge Brierly falls in love with vacationing Blue Grass aristocrat Frank Layson, when he stops Horace Holten from defrauding her of her coal-rich lands. For revenge, Holten tells moonshiner Joe Lorey, who loves Madge, that Frank is a revenue officer. After Madge rescues Frank from Joe's attack, they go to Frank's home, where he teaches her reading and writing, and she rescues his racehorse, Queen Bess, from a fire set by Holten. Because Frank has nearly all of his family's money riding on the big Kentucky race, Holten gets Frank's jockey drunk. Madge, discovering this, disguises herself and rides Queen Bess to victory. She leaves for home unnoticed, and comes across the Night Riders chasing Lorey. After she persuades them that Holten killed her father years earlier, and was responsible for Lorey's attack, they chase Holten who falls from a mountain and dies. Years later, Madge's and Frank's children play at feuding.
