Over twenty years, three Irish traveller families become engulfed in a cycle of violent revenge, taunting each other with video messages, risking the families’ honour and placing big-money bets on the result of bare-knuckle fights between the clans’ best fighters. Two men, two neutral referees, a country lane. No gloves, no biting, no rests. The last man standing wins, takes home the money, and more importantly, the bragging rights. Knuckle is the story of Irish traveller, clan head and champion bare-knuckle boxer James Quinn McDonagh. It’s a journey from his grandfather’s barrel-top caravan to the modern life of the travellers, a brutal story of threats, guns, and fists, an antidote to the cleaned-up portrayal of travellers in the media, a gritty and truthful insight into a hidden world.
