The Broncho Buster (1927)

Maj. John Furth, a Southern race-horse owner, borrows money to enter his prize racehorse Blue Bird in a race back east, hoping to win enough money to replenish the family fortune. A crooked horse trainer, planted by the man who loaned Furth the money and who wants to marry his daughter Barbara, claims that Blue Bird is a "man killer" and must be shot. Charlie, a neighboring miner who also loves Barbara, doesn't believe it and takes Blue Bird to his mine. Complications ensue.
