In the 1960s, Beijing educated youth Chen Zhen (played by Feng Shaofeng) and Yang Ke (played by Dou Xiao) came to the Elun grassland in Inner Mongolia to join the production team of the Mongolian herdsman Bilige (played by Basen) and his daughter-in-law Gasmai (played by Anghanima), and began a herding life for several years. In the process of contact with the wolf pack, Chen Zhen, with a strong curiosity, gradually understood the animal and even had the idea of raising a little wolf himself. The Mongolian people revere wolves and love the grasslands, while the Han people utilitarian plundered the land, which led to a "war" between wolves and humans. The production team headed by the field director Bao Shungui (played by Yin Zhusheng) finally launched a wolf-killing campaign, which put the relationship between wolves and humans into a tense situation... The relationship between nature and humans has also encountered unprecedented challenges. The film is adapted from Jiang Rong's novel of the same name and took 5 years to shoot.
