On the quiet backroads of rural Armagh, fierce competition rages in the sport of 'road bowls' - where competitors hurl steel cannonballs down country lanes, trying to compete the course in the least number of shots. But 'throwing bullets' is not merely for personal pride and family honour, there are local and national championships to aim for, and when two throwers go head to head there can be thousands of pounds in cash at stake as spectators bet on the outcome. Thomas Mackle, the current Ulster and All-Ireland champion is the man to beat, and his biggest rival, Cathal Toal, is determined to take his titles off him. Over the course of a road-bowling season, the film follows the rival camps as they vie to outthrow each other on the quiet back roads of the Orchard County.
