Racing Luck is a 1948 American comedy romance sport film directed by William Berke and starring Gloria Henry.
Saddled with debts after her father's death, Phyllis Warren's most valuable properties are a pair of thoroughbreds: Flasher, which her little brother "Boots" trains and rides, and Charm Boy, which doesn't seem to run well unless Flasher is in the same race.
Charm Boy is bought at a Santa Anita claiming race by rich trainer Jeff Stuart as a gift to Natalie Gunther, his sweetheart.
With a big stakes race coming up, Natalie discovers that Charm Boy won't run unless Flasher does as well.
A barn fire results in an injury to Boots, but he still manages to ride Flasher to victory and win Charm Boy back for his sister.
