To ensure the security of a ten-billion-yuan acquisition, Su Bai, chairman of Yunding Capital, disguises himself as an intern and secretly joins the lower ranks of Xingmang Technology to investigate its accounts. He discovers that the company's general manager, Lin Shaojie, is secretly plotting to transfer its core technology patents and strip the company of its assets. Along the way, he meets Xia Meng, a grassroots employee who stands by her principles, and Chen Gang, a veteran engineer. In the end, Su Bai gathers all the evidence and works with law enforcement to bring the offenders to justice. He completes the full takeover of Xingmang Technology, protects its core technology and the rights of all its employees, and puts the company back on the right track.
