At a classmate gathering on the Peking University campus with the theme of "opposing war", Mu Yu, a doctoral student at the School of Literature, met Bian Hongqi, who claimed to be a literary youth. Bian Hongqi can write poems, especially improvised poems. His unrestrained talent makes no one associate him with people who make and sell fake diplomas. Because of Mu Yu, Bian Hongqi met Meng Yiming, a doctoral student at the Peking University Law School, who lived in the same room with Mu Yu. When Meng Yiming's wife Sha Xiu, who lived far away in his hometown, came to Beijing, Mu Yu, Bian Hongqi, and Meng Yiming rented a bungalow together and began a life as a "Beijing Drifting Clan" of young people from other places. With Sha Xiu, the lives of the three outsiders who pursued their own dreams began to come alive, especially Meng Yiming's life, which was moist and comfortable. Among the three people, except for Mu Yu who was immersed in his literary dream and rarely went out, Bian Hongqi and Meng Yiming rarely stayed at home. Bian Hongqi had to make money and go out to sell fake diplomas with fear and trepidation. Meng Yiming had to substitute for graduate students and complete extra tasks assigned by the leaders of the institute at any time. In the busyness, no one cared about Sha Xiu's feelings and the changes that had quietly taken place. Sha Xiu was a kindergarten teacher in her hometown and was good at singing and dancing. Looking at the three men around her busy with their dreams, Sha Xiu couldn't sit still. But when Sha Xiu finally found a job washing dishes in a restaurant, Meng Yiming said he would not let her do it, because in Meng Yiming's eyes, it was a shameful thing. Sha Xiu was not allowed to find a job, and Meng Yiming did not have more time to accompany Sha Xiu. When the married Bian Hongqi was often visited by the Beijing girl Shen Dan, and Meng Yiming was loved by a beautiful female graduate student, Sha Xiu's psychology began to lose balance. In order to escape the "severe crackdown", Bian Hongqi moved out of the shared bungalow courtyard. After Bian Hongqi settled down outside, Mu Yu went there once as agreed, and it was simply not a place for people to live. At this time, a "blockbuster bomb" exploded between Meng Yiming and Sha Xiu. Shaxiu is pregnant, but she says the child is not Meng Yiming's. Whose could it be if it's not Meng Yiming's? Mu Yu? Or Bian Hongqi? When Shaxiu said it was Bian Hongqi, Bian Hongqi was eventually unable to escape the crackdown and was taken away by the police. Mu Yu regretted that he had "let the wolf into the house", and Meng Yiming, struggling in pain, left without saying goodbye and returned to his hometown. A few days later, when Meng Yiming appeared at Beijing Station, Mu Yu, who received a text message, came to pick him up with Shaxiu. In the biting night wind, Meng Yiming, who decided to leave Beijing and return to his hometown to develop, hugged Shaxiu tightly in his arms. Shaxiu, with tears in her eyes, removed the blockage in Meng Yiming's heart. All the unhappiness was washed away by the joy of returning home, and the silent cold night was filled with the roar of a singer from another place who pursued his dream, "The light on the golden mountain in Beijing shines in all directions..."
