Plot synopsis: The movie story is born out of Sima Qian's "Historical Records: Biography of an Assassin", which originated from Yurang, one of the four great assassins in ancient China, and revolved around the allusion that "the scholar died for his confidant". The adapted story tells that in a turbulent period of the separatism of the nations, Lian Qi, in order to avenge the slaying of the king, tolerated his name, and from this led to a complex entanglement of love, and the ultimate choice of his family, the world, and his personal morality.
