Patrick Sheehy, an Irish immigrant and down-on-his-luck racehorse owner, has been racing horses for over 40 years. Out of nowhere, a rookie trainer, Carl O’Callaghan (another Irish immigrant), brings Patrick’s flawed and almost forgotten thoroughbred to victory at the Dubai World Cup. Kinsale King is crowned “the fastest horse in the world.” Invitations to some of the sport's biggest races flood in (including invites from The Queen of England and The Monarch of Dubai). Success and fame are followed by the hard-hitting reality of what it means to survive in the Sport of Kings. As they travel around the world to five Group 1 races, Carl, Patrick and Kinsale King come to learn where THEY fit in and what winning really means as they form a life long friendship.
