In a small clinic in the rain-drenched city of Kaili, two preoccupied doctors live ghost-like lives. One of them, Chen, decides to fulfill his dead mother’s wish and sets off on a train journey to look for his brother’s abandoned child. His partner in the clinic, a lonely old lady, asks Chen to find her old lover, and give him an old photograph, a shirt and a music cassette. But on the way, Chen passes a mysterious town called Dangmai, where time is not linear and people’s lives complement each other. Here, Chen experiences the past, present and future. It’s unclear whether this world is the doctor’s dream, or the other way around.
In the mystical province of Guizhou, there is a small county clinic surrounded by fog. At the Kaili clinic, there are two doctors who live quiet, lonely lives. One of the doctors, Chen Sheng, embarks on a journey by train to find his nephew, who had been abandoned by his brother.
