The relationship between the wealthy Jiang Chengtian (played by Yue Hua) and his eldest son Jiang Yuan (played by Lai Yiu Cheung) has always been tense and discordant. In addition, their business philosophies are very different, which makes their relationship even more hostile. Not long after his mother's death, his father married his stepmother Li Qiuping (played by Guan Juying). Jiang Yuan made a scene at the wedding banquet and had a feud with his uncle Li Qiuqin (played by Chen Guobang). Jiang Yuan resolutely decided to leave the famous family and founded Delijia Investment Co., Ltd. with his capable subordinates Ding Manzi (played by Wu Dingxin) and Zhong Xiaoyang (played by Huang Haoran). Jiang Yuan was ashamed of his father's despicable means to suppress the small business Abeya. He made a desperate attempt to invest in Abeya, but Zhong Xiaoyang turned against him and ended up bankrupt. Jiang Yuan disappeared. A year later, Jiang Yuan appeared in Hong Kong and met his ex-girlfriend Guan Huala (played by Shiu Maggie) and her son Gao Xing (played by Zheng Junhong) again. Guan Huala handed over half of the shares of the mobile app company to Jiang Yuan according to her late husband's wishes. Jiang Yuan took advantage of the mobile app boom to return to the business world. In the seemingly prosperous upper class society, family, friendship and love seem to have become means of competition. Who is the real winner in the secret battle among the famous families?
