In order to crack a telecommunications fraud case involving a huge amount of money, the former deputy captain of the criminal police team, Kuang Zhong, was ordered to urgently set up the tenth detachment, the anti-fraud detachment, with Zhu Xining, Marseille and others to fight wits and courage with the increasingly rampant fraud criminal groups. They played their respective strengths and tried their best to protect the property safety of the people. In the process of handling the case, they were not understood and even scolded by the victims, and faced many difficulties. The team members truly felt the heaviness and difficulty of the three words "anti-fraud". Under the leadership of the captain Kuang Zhong, the team members became more tacit and solved one fraud case after another. In the process of solving the case, Kuang Zhong discovered the mastermind behind the fraud case - the "gold owner", the leader of the fraud gang from abroad. Kuang Zhong tracked the whereabouts of the "gold owner" at all costs. After several twists and turns, he finally wiped out the fraud dens set up abroad.
