<p> 沙展唐飞（谢霆锋 饰）办案追求快狠准，行动极为猛烈。在追捕疑犯张日东时，卖命追车超车，最终引发一场连环车祸，张日东一伙除却张自己重伤昏迷，其他全部当场死亡，然而在车后厢，唐飞发现被自己飞弹射死的小女孩，不禁愕然。

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 二个月后，张日东苏醒，法院正式排期起诉他。检控官高敏（张静初 饰）正是当日被误杀的小女孩的母亲，与丈夫离婚的她如今把所有的爱都倾注在小女儿丁玲身上。活在愧疚感中的唐飞这两个月中也一直关注着丁玲，看见丁玲便又仿佛看见当日悲剧。
