Unbridled and enjoying life was a hero and model for his kin. One day something new appeared in the quiet Wild Valley, a small light in the dark that changed Mustang's entire life. A curious horse wanted to check what or who it is. It turned out that they are people who camped in the forest, who quickly imprisoned a beautiful animal. Tethered and confused, Mustang decides to free himself at all costs.
