Ke Bei, a retired special forces soldier, was inexplicably involved in a gangster deal during a trip abroad. In order to protect his wife and children, he fought against the gangsters, but unexpectedly ran into his old enemy, the killer Wild Dog. His wife and children were abducted, and their whereabouts were unknown. In a money deal, he was in a dilemma between choosing between family and country. Ke Bei was unwilling to take risks with his comrades, and even more unwilling to harm the interests of his family and country for the sake of his small family, so he decided to go deep into the tiger's den alone and fight alone, but he didn't know that the iron-blooded team of that year had already quietly assembled.
