In the family building of the National Taxation Bureau, two bizarre thefts broke the dead silence before the change of power, and the fringe unit Chang Anmin was deeply involved in the whirlpool. The deputy director's home appliances were soaked in water and the office safe was broken into. An Min was locked up by the criminal police for squatting late at night and became the number one suspect. Relying on his hidden investigative identity and excellent professional skills, Anmin turned against the client in the power game, uncovered the shocking layout behind the theft, and climbed from the fringe to the pinnacle of power step by step.
