Seasoned jockey Jackson has weathered decades of races on the riding circuit, but he now finds himself facing what could be his last season as his health deteriorates.

Shot at a live racetrack and with a keen eye for veracity, Jockey gives us an achingly personal window into a world we′ve never seen up close before, where fortunes are flipped upside down from one moment to the next and the freedom of riding comes at a grueling physical price.
