改编自历时20年不懈努力侦破的“1998.9.2”惊天命案。

马建新（陈建斌 饰）是火车修理厂里的一名员工，虽然平日里沉默寡言毫不起眼，但他对待工作却格外的认真和踏实，是一个靠谱的青年。某日，工厂派马建新前往铁路系统学习班深造，在那里，马建新结识了名为李卫华（吴越 饰）的老师。
巧合的是，马建新和李卫华都十分喜欢和菊花茶，这一共同点迅速拉近了两人之间的距离，随着时间的推移，一种别样的情感在两颗心之间滋生了。然而，李卫华的身体状况十分糟糕，常常莫名昏倒，更糟糕的是，她患上的疾病让她注定无法成为一名母亲。可是，马建新对此却并不在意，执意和李卫华携手步入了婚姻的殿堂。

With his directorial debut actor Chen Jianbin walks in the footsteps of A Touch of Sin, No Man’s Land, and Black Coal, Thin Ice and offers a hard-edged mainland noir where kindness and cruelty, madness and reason, greed and humanity all struggle for dominance and the fool might not be who you think . The hook here is Chen’s amazing performance as the simple, slightly crude Latioazi, a goat farmer who has a son in jail. When a young mentally handicapped man follows him home one day and enters his life, it sets off a blaze and a chain of events follows, which bares China’s class divide raw. His random act of reluctant kindness invites a parade of strangers and grifters all intent on draining Latioazi of what little he has.

A man must attempt to clear his name after a theatre puts on a play that accuses him of committing a 30-year-old murder.
