In the cold winter of 1968, Zhao Hongyi, an educated youth from Beijing, had to suppress his desire for freedom (independent caves, cultural relics system) and fight against collective rules in the ice and snow on the border. During the days and nights of transforming Yingzuankan, he and the girls went from being suspicious of each other to sharing life and death, shielding each other from the gunfire of black market transactions, and exchanging souls in the fog of the times. When an overseas smuggling group targets Hot Spring Valley, Zhao Hongyi uses Tai Chi to shatter the conspiracy, but he has to choose between the justice of his family and the love of his children - in the torrent of the times, can he protect his lover and the fire of civilization? A bloody romance blossoms on the ice field. This is a legend about survival, faith and forbidden love among educated youth.
