After his wife Xiaolin (Jing Tian) passed away, Mi Yifan (Lu Yi) and his five-year-old son Xiaole (Mini Bin) depended on each other for survival. Before Xiaolin died, he left a promise that he would return to the world in the rainy season next year, and the father and son were skeptical. Unexpectedly, Xiaolin really appeared in the rainy season the following year, but he had no memory. The broken family was reunited again. Although they had doubts, Mi Yifan and Xiaole still gave their love to Xiaolin without reservation. Gradually, Xiaolin really integrated into the family and accepted the role of wife and mother. The happy family seems beautiful, but can the dead really be resurrected? Is this amnesiac Xiaolin really their relative?
