Leslie Heart is an ambitious woman living in an affluent society where status and money matters the most. Her life takes an unexpected turn when she inherits an old rundown horse named Fiddler. Leslie sees this as an opportunity to prove her worth to her elitist friends by training the horse for prestigious racing events and winning big bets.
Initially, Leslie struggles with training the stubborn animal and fails in many attempts. She hires an experienced horse trainer, but he is unable to get through to Fiddler. Frustrated and running out of options, Leslie reaches out to her ex-lover and former celebrity jockey, Tommy, for help.
Tommy, who has fallen from grace and is now an outcast in the racing world, agrees to help Leslie under the condition that she executes a long-term con to take revenge against his former competitors. Leslie, desperate to succeed, agrees without fully knowing the extent of Tommy's plan.
As Tommy trains Fiddler to be a competitive racehorse, Leslie gets more and more entangled in the con. She begins to sabotage other horses and pay off their jockeys to ensure Fiddler wins every race. However, her actions lead to disastrous consequences, and soon, Leslie finds herself in deep trouble.
The Fiddling Horse is a dark comedy that explores the lengths people go to improve their circumstances, even if it means engaging in deceit and morally questionable activities. The movie showcases the complexities of ambition and the fine line between success and failure.
