Aspiring teenage jockey Frankie Darro (as Frankie Reynolds) buys a crippled colt for $4.85 and nurses him back to health. "Racing Blood" has been in young Darro's family for generations, and he will eventually run his horse "Trouble" professionally. Guess you could call him the little colt that could. After six months, Darro cures "Trouble" with mud packs and begins training him to be in the Big Race. Eventually, Darro wins a race against his older brother James Eagles (as "Smokey") and his horse "Dancing Boy"...
The brothers are honest jockeys, but crooked Matthew Betz (as Tex O'Donnell) and his gang want the races "pulled" (meaning fixed) in order to rake in the dough. In a romantic subplot, Darro mentor Kane Richmond (as Clay Harrison) romances the jockeys' sister Gladys Burke (as Phyllis). As if to illustrate how routine everything seems, perpetually inebriated Arthur Houseman (as Legs) shows how his drunk act steals scenes, and superstitious Fred "Snowflake" Toones (as Sam) finds the name "Trouble" frightening.
