In Scotland, King Fergus of Clan Dunbroch presents his young daughter Merida with a bow for her birthday. While practicing, Merida encounters a will-o'-the-wisp. Soon afterwards, Mor'du, a giant demon bear, attacks the family. Merida escapes along with her mother Queen Elinor while Fergus fights off the bear at the cost of his left leg. Years later, Merida has become a free-spirited teenager and an older sister of identical triplets: Hamish, Harris and Hubert. Elinor informs her that she is to be betrothed to one of her father's allied clans.
