The three lords of the kingdom – Dingwall, Macintosh and MacGuffin – are the unruly, overzealous leaders of their respective clans. Though once warring factions, they have been united under the sword of King Fergus and held together by the diplomacy and political savvy of Queen Elinor. The clans are summoned to Castle DunBroch to compete in the Highland Games, but the lords are soon outraged when Merida defies a sacred tradition. The clans fall back to their history of fervent feuding, which threatens the fragile peace of the entire kingdom.
