Three men were involved in a horrific rape-murder case in Xilong city that left a family of five dead and still remains unsolved. Since then, the three have lain low in the provincial capital, Xiamen - Xin Xiao Feng as an auxiliary police detective, Yang Zi Dao as a taxi driver, the simpleton Chen Bi Jue as a fisherman-rafter - and secretly cared for Wei Ba, the daughter of the raped victim, as an act of personal redemption. When Xiao Feng gets a watchful new boss - Yi Gu Chun, also from Xilong - he starts to suspect that their days could be numbered.
