Stoic truck driver Jinpa picks up a silver dagger wearing hitchhiker in the desolate Kekexili plateau. The stranger suddenly reveals he’s going to kill the man who murdered his father.

Tharlo is an orphan. Now grown up, he makes a living as a sheep herder in the village. He has grown a ponytail, so people simply call him “Ponytail”, since nobody remembers his real name anyway. Tharlo has a remarkable memory. He remembers so many things, except his own name. He is now in his forties, and he has yet to have his first woman. Now Tharlo goes to town to take a photo for his identity card. He meets a girl in the barber’s shop who changes the course of his life. He embarks on the journey to find his true self. He sells all his sheep and those entrusted by other villagers to him for care, and decides to use the money to go out into the world with the girl, only to find himself being deceived and cheated by her. Ironically, in his journey of self-discovery, Tharlo has lost his sense of self. As he witnesses in the mirror his ponytail being cut off and leaving him bald, he can no longer see himself as a man with a history that he recognizes.
