In the future world, humans have developed bionic people who are physiologically the same as humans. The only difference between the two is that they can be implanted with "initial obsession". Due to the rapid development of the industry, some people began to use it for illegal activities. The government finally issued a "Bionic Man Ban". The government set up the "Bright Eyes Investigation Department" to cooperate in the search for undiscovered bionic people in human society. Investigators Cheng Nuo (played by Song Weilong) and An Qiu (played by Wen Qi) started their work under the leadership of team leader Wan Guofeng (played by Zu Feng). The two went from disliking each other at the beginning to being able to cooperate tacitly to complete the case. In this process, the secrets hidden by the two gradually surfaced.
