The Bao family has adopted Pan Langqing (played by Guo Jinan), the son of Pan Zhong, a fellow villager, for many years. Bao Wenlong (played by Zheng Yijian), the eldest son of the Bao family, is a sympathetic brother to him. Huang Tian (played by Zheng Shaoqiu), the head of Zhongtian Group, plotted against him and was investigated by Wenlong, an agent of the Commercial Crime Investigation Division, but became a close friend with him. Lang Qing, who was eager for quick success and quick profit, illegally made quick money, causing Wenlong, who came to dissuade him, to be suspended, putting the Bao family in trouble. Pan Fu asked his old friend Huang Tian for help, and Lang Qing was able to enter Zhongtian Group. Wenlong, who had no hope of reinstatement, was appreciated by Huang Tian and recruited into Zhongtian, thus entering the business world. Wenlong met a strange girl Lin Zhenlie (played by Chen Songling), and the two began to fall in love. Lang Qing was used by someone to sell Zhongtian's business secrets, which aroused Huang Tian's suspicion. In order to gain Huang Tian's trust and gain power, Lang Qing began to pursue Huang Tian's daughter Huang Lei (played by Guo Aiming). But Huang Lei broke off the engagement with Wenlong because of him, and intervened in the relationship between Wenlong and Zhenlie, putting Wenlong in a dilemma. Lang Qing, who suffered the humiliation of the broken engagement, started a revenge plan with Huang Tian's opponents. In the business world, the situation is ever-changing. Who can predict the gains and losses?
