Chen, a preoccupied doctor working in a small clinic in the rain-drenched city of Kaili, decides to fulfill his late mother’s wish and sets off on a journey to look for his brother’s abandoned child. His partner in the clinic, a lonely old lady, asks him to also find her former lover, giving him a photograph, a shirt, and a music cassette. On the way, Chen passes through a mysterious town where distinctions between past, present, and future appear to slip away.
