Gao Xiang is a senior member of insurance. He runs all kinds of criminal undertakings and plays with the police. There was a gun robbery in the Chengmen River, which lost 1.5 million US dollars. The perpetrator was a big boy who committed the cross-border crime. Because the money was insured by Xiang's insurance company, Xiang therefore investigated the case and determined that there must be an insider. This triggered Xiang's criminal idea. If he could ambush the escort company and provide him with the driving route of the refund car, he could rob the money at any time. Xiang then launched a plan and hooked up with the female manager of the escort company.
