In 1997 in Northeast China, the old industry was facing the farewell era. Yang Beibing (played by Bu Guanjin), an 18-year-old technical school girl, was full of vigor and righteousness. She often took a group of sisters to fight everywhere. After breaking into the men's bathhouse, Yang Beibing ran into her childhood friend Yuyi (played by Liu Chang) who was taking a bath. She was moved by him and quietly hinted and pursued him. Unexpectedly, Yu Yi fell in love with the southern girl Ziwei (played by Li Meng). Yang Beibing failed to fight, but was also attracted by Ziwei's mature and unique temperament. However, danger was quietly sprouting. Yang Beibing and Yu Yi worked in a disco and accidentally witnessed the murder scene of the boss Lei Guan. In fear, Yang Beibing discovered that Ziwei and Lei Guan (played by Huang Jue) had an intimate relationship. Young desires mixed with danger pushed Yang Beibing and Yu Yi into the cruelty of the adult world. After being bruised and battered, Ziwei died accidentally, and Yang Beibing left Northeast China. Many years later, Yang Beibing and Yu Yi met again, looking back at the youth that whizzed by, and the two gradually let go of their pain.
