Kevin Heffernan was a giant amongst GAA men. A giant with a brilliant mind who repeatedly warned everybody that he would not let his own mother get in the way of him winning one more game of football. Heffo was deeply admired and absolutely feared like no other. And like no other manager in the history of the GAA, his strength of mind and brutal toughness as a leader raised an army that was called his own - Heffo's Army. Heffo: A Brilliant Mind tells the Kevin Heffernan story for the first time. It's the story of a boy with the biggest dreams, and a man who lived with triumphs and the greatest regrets. It's the story of a club, and how Heffo and St Vincent's GAA club revolutionized the game of Gaelic football and changed the face of Dublin football forever. It's the story, too, of a great war. Heffo: A Brilliant Mind dramatically re-enacts the battles that Kevin Heffernan fought over four decades as a footballer and a manager in a long and punishing war with Kerry. It is a war waged by one man with the courage and fearlessness of a true giant.
