In 1925, there was an undercurrent surging on the beach in Shanghai. Lin Han, a small patrolman in the French Concession, accidentally rescued the orphan of a Green Gang boss who was being hunted and got involved in a gang fight. With his business vision and courage that transcended the times, he emerged from the cracks of giants such as Huang Huangrong and Du Yuesheng. From dock freight to banking and finance, from department stores to film companies, Lin Han has established a business empire that spans industry and culture. When the Battle of Songhu broke out, he made a choice between business war, friendship and family, and finally became the uncrowned king in charge of Shanghai.
