From time immemorial, the myths and legends shroud picturesque foothills of the Scottish mountains with a mysterious veil. A skillful archer Merida has to choose her own path in life, and one day she refuses to follow the ancient traditions of the kingdom, defying powerful Scottish clans and their leaders: a clumsy Lord MacGuffin, a sullen Lord Macintosh and a grumpy Lord Dingwall. Merida's reckless actions threaten to plunge the kingdom in the chaos, and then she goes for advice to an eccentric recluse, who, instead of helping, imposes a dangerous spell on Merida. The young princess will have to rely only on her own courage to overcome the powerful magic and defeat the worst beast of those found in the mountain valleys.
