Based on the commercial situation in Shanghai in 1930s, the story tells the bumpy and bizarre life experience of Zhang Tianyun, the fourth generation descendant of the Red Gang. Around "Tong Yi Chang", an old-fashioned clothing brand, two generations of leaders launched a soul-stirring commercial war with Shanghai black forces, big capitalists and Japanese chaebol. In the play, zhang tian Yun and Wang Renchang changed from entrepreneurial brothers to rivals in shopping malls and love, and even became sworn enemies. Finally, they fell into the abyss of power struggle, hatred and resentment.

In order to save his family business, Zhang, the third generation head of Tongyichang, reluctantly borrowed usury concession from the Japanese to open a shop. However, the business is bleak and difficult to operate. In order to repay the loan, Zhang tried his best to win a big order for Yuan Shikai's government to make official uniforms. Zhao Xueming and other revolutionaries assassinated the anti-government envoy. Tong Yichang was implicated in this incident, and Zhang was betrayed by his brother, who was determined to be the best and spilled blood on the garment factory.

The death of his father awakened Zhang Tianyun's responsibility to Tong Yichang and his family, and at the same time aroused his desire for revenge and overthrew Tong Yichang. In less than a year, zhang tian Yun and Wang Renchang, with extraordinary perseverance and extraordinary intelligence, finally set up their own brand in Shanghai: "Yunchang" suit shop.

In order to defeat the cunning competitor-Toyo Garment in Kawakami, Zhang Tianyun endured great emotional pain: he used his daughter Yoko in Love for Himself in Kawakami, and with the help of Zhao Furu and Zhao Xueming, he finally gained the controlling right of Toyo Garment and revived the family brand "Tongyichang".

The "unified field" succeeded! Zhang tian Yun and Wang Renchang won their honor. Wang Renchang, who had been silently in love with Yoko, could no longer bear the betrayal of love and psychological torture, and finally broke with Zhang Tianyun completely. "Tongyichang" is once again in crisis, and the two brothers launch a new round of life-and-death struggle on the beach! At this time, the Japanese army invaded, Shanghai fell, and the revenge of the Chuanshang family also pointed to "Tongyichang". Faced with national justice and personal grievances, zhang tian Yun and Wang Renchang finally made a conscientious choice.
