The Kentucky Derby (1922)

Dirty work is afoot in old Kentucky when a rival decides that his horse will have a better chance of winning if the son of the owner isn't around, so he has him shanghaied onto a tramp freighter and gets the jockey in his debt through a crooked gambling game. Airplanes, ship-wrecks, sea storms, kidnapping, frame-up and much skullduggery prior to the race.
