Ren Jiahua is a skilled thief. He and his girlfriend An hijacked the money transport vehicle and obtained a huge amount of stolen money. Detective Li Tiejian was responsible for investigating the matter and eventually locked the suspects on Ren Jiahua and An, but there was no solid evidence to accuse them. Li Tiejian detained Ren Jiahua and An, but he only had 48 hours. If the two failed to plead guilty within this period, they would completely escape the law. In order to get testimony, Li Tiejian was determined to torture them, but this trick was useless for the battle-hardened Ren Jiahua and An. Ren Jiahua even bit back and accused Li Tiejian of violent law enforcement. In the end, the police decided to join hands and bring the two to justice with their wisdom.
