Few sports have such cultural resonance with the people of Ireland as horse racing and even fewer share such a long and rich history. Ireland's fascination and unique connection with horsemanship and the Sport of Kings spans the centuries. A study of Irish horse racing through the ages provides a unique window on this country over a remarkable span of time.

The origins of the sport in Ireland can be traced to before the Battle of the Boyne in the 17th Century. The traditions and knowledge built up over the past 300 years have shaped a sport and an industry which today leads the world.

Given Ireland's pre-eminent position in the world of racing the time is right to tell the story of how it all began and chart the progress of horse racing from its' beginnings to the modern era. "In The Blood" is a feature documentary which re-lives some of the golden moments in Irish horse racing and presents an insight into a sporting culture which is part of the fabric of our society and is winning the world over in the International sporting sphere. The film offers a unique glimpse into the worlds of Flat and National Hunt Racing, following a trainer through the National Hunt Season to Cheltenham and Aidan O'Brien's build up to the Irish Derby.
