Ah Ying (played by Janice Man)'s father died unexpectedly. In his last words, he asked her to open the freezing device in the laboratory. Inside was her biological mother Fang Yingzhi (played by Janice Man) who had been frozen for 20 years. Although they were two generations apart, they looked similar in age, so Ah Ying began to take Ah Zhi to adapt to modern life. Ah Zhi, who woke up, was always immersed in memories. The sweet time she spent with her lover in her youth, Ah Ying's biological father Zhang Weijie (played by Aarif Lee), was vivid in her mind. The two young people liked their brother Leslie Cheung. Ah Zhi often listened to Ah Wei playing guitar and singing "Love for You". The two went to see their brother's 1989 farewell concert together, but they had a car accident on the way... The past is like smoke. Now Ah Zhi, who has woken up, is determined to find Ah Jie. Ah Ying, who has returned from studying in the United States and is full of modernity, is also brought back to the nostalgic 1980s by her mother's memories. She is deeply moved and begins to help her mother find the traces of her biological father now...
