Jia Dawei (Zheng Hao) is a grocery store owner who is kind-hearted and a little timid. On this day, his wife quarreled with him over trivial matters. Dawei was accustomed to such boring quarrels. After his wife left on a business trip, he planned to do something to surprise his wife when she returned home. After thinking for a long time, he decided to buy a new Simmons mattress. When he happily transported the mattress home, he turned around and found a comatose girl Lin Jing (Liu Tingyu) lying on the mattress, which stunned Dawei. At this time, Ren Tianyi (Liu Hu), who was released from prison, was looking for the missing Qiu Yu (Xiang Neng) on the street, but his mind repeatedly flashed the long talk between the warden and him before he was released from prison.

Yu Taiping (Xue Gang) and Zhang Xiaolei (Dong Jingchuan) were hired to find evidence of Jia Dawei's derailment. Everything is confusing...
