Cast & Crew
Frankie Reynolds, the younger brother of jockey Smokey Reynolds, buys a colt named "Trouble" and heals a bone malady in his leg so that he can train him to race. Months later, Trouble enters his first race against his twin "Dancing Boy," who belongs to Smokey. Crooked gambler Tex O'Donnell asks Smokey to pull his horse, but he refuses, and Tex loses $10,000 when Trouble wins. Tex then frames Frankie by ordering his bibulous henchman, "Legs," to give Frankie $500 to put in the bank for Smokey, thereby giving the appearance that Frankie paid Smokey to let him win. Smokey is then accused of pulling his horse and betting on his brother's. The judge rules Smokey off the racetrack for life, and Frankie must now beat "Bubbling Over," the best horse in the country, to prove that Smokey is innocent. Newspaper headlines tout the need to rid horseracing of the alliance between gangsters and gambling. Meanwhile, Tex schemes to insure a win for Bubbling Over, and after Frankie's horse loses, Smokey attempts suicide and is hospitalized. Frankie and Smokey's sister Phyllis and her fiancé, Clay Harrison, try to abduct Legs from a bar as a witness for Smokey, but Tex intervenes. Clay and Frankie are knocked out, and Legs is taken by Dopey, a gang member. After Trouble is advertised as a "one-man horse," Dopey tries to poison him, but inadvertently poisons Dancing Boy instead. Dopey then kidnaps Frankie, and headlines announce that police have executed a raid on local gambling joints in search of him. When Dopey complains of stomach pain, Frankie, who used to study medicine, writes him a prescription that is really an "SOS." He then tries to escape, but is shot in the scuffle. After Dopey goes to the pharmacist, who reads Frankie's call for help, the police arrest Dopey, then locate Frankie and place him in an ambulance. Frankie drives the ambulance to the race, nearly passing out, and arrives at the track in time to mount Trouble for the race. During the race, the police arrest Tex, and Frankie wins the race and collapses. In the hospital, Frankie recovers next to Smokey and gives him his prize money, which Smokey in turn gives to Phyllis so she can marry Clay.
