Gei Libao, the former Olunchun hunter raised more than 100 Hunting horses in the traditional way. Although hunting was banned, Libao occasionally went into the mountains, not for hunting, but for the ancestors' hunting culture. Libao's son Liang Liang and his partner are inseparable from the forest, and are more enthusiastic about modern extreme sports. They have formed an off-road motorcycle team, which is consuming the youth of the mountain. One day in summer, Libao's horses was hit by a poacher's bullet, which caused a series of cultural collisions.
