Daughter of a clan chief, Naya is bolder than the other girls but shunned by the boys because of her unusual appearance, Naya often wanders alone through the vast grasslands where her people herd domesticated cattle, and hunt wild horses for their meat. But Naya dreams of creating a different kind of relationship with the magnificent creatures. One day, while out roaming by herself, she discovers a filly with a chestnut coat as uncommon as her own head of red hair. With time running out before she is called to assume the responsibilities of adulthood, Naya embarks on a quest to fulfill her vision of galloping with the filly across the boundless steppe. Unwittingly, she sets in motion forces and events that will change forever the future of humans and horses alike.
