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.

Big Steve Halloway, gambler and proprietor of New York's Horseshoe Cabaret, is in desperate need of money. He arranges for his fellow bookies, especially Sorrowful Jones, to each pay him $1,000 for his racehorse, Dream Prince, to lose. With all bets being placed at the window, Sorrowful encounters a gambler, having lost $500, wanting to place his bet but unable to come up with $20. Instead, he places his little girl, Marthy Jane, as security, or in bookie's terms a "marker". "Marky", as she comes to be known, winds up under the care of Sorrowful Jones and his lady friend, singer Bangles Carson.
