Synopsis

"Ulubu Iron" in Oroqen is translated into Chinese as "Gushan". It is an Oroqen township in the north of Inner Mongolia.

A former hunter contracted Lippo’s horse farm in the mountains and keeps more than 100 Oroqen hunting horses in a traditional manner. Although hunting is banned, Ge Libao occasionally goes into the mountains, not to hunt, but to abide by the hunting culture of his ancestors. Liangliang, Libao’s son, and his partners are inseparable from the forest, but they are more enthusiastic about modern extreme sports. They have formed a cross-country motorcycle team which consumes their youthful passion.

One day in the summer, when Lippo’s horse is shot by a poacher’s bullet, the Ulubu Iron sky is covered with a layer of gray.
