Pride of the Blue Grass
"In the Maddening Roar of Pounding Hoofbeats...Danger Lashes the Kentucky Turf...and a Girl's Throbbing Lips Seek a Man;s Burning Kisses!"
A girl owns a horse, and hires a boy as a trainer. The horse enters a race and is injured. The boy takes job at another stable and is semi-seduced by the stable siren. The girl finally rehabilitates the horse then enters it in a big race.
