Billy Garrison, a successful young jockey, rides the favorite "Sis" in the Louisville Derby. He does not ride with his customary vigor and dash. He feels "doped" and entirely out of condition and as a consequence "Sis," instead of winning the race, trails in last under the wire. At the stables he is accused of throwing the race, but denies it.
