A man in dire straits flees to Golmud, Delingha, and Ninghu on the Qinghai-Tibet Plateau, only to encounter a cycle of reincarnation much like the one in his previous life. Under the mysterious influence of "particles," past, present, and future merge into one. All things intersect, interfere, and change in an instant. The one thing that never changes is the love that can reach the highest point in the universe.
