In the 1970s, three children were born in the same hospital in the north. Twenty years later, they became best friends. That year, Haibo and Fangshan University just graduated, and Roger was not willing to be just a coolie. It was a national craze for selling steel. The three of them are full of blood and dream of making a fortune, and come to a strange city thousands of miles away to sell steel. As a result, they were not rich when they were young, but they were used by swindlers and involved in steel fraud cases. The friendship between the three people has gone through layers of hardships and tests and turned into a lifelong struggle.

The adventure was not entirely fruitless. They met Su Wen's sisters who lived in Su Li, another country. After returning to the city where they lived, Fangshan and Roger began to pursue Sue's sisters, but Su Li actually liked Haibo. Although he never made it clear, gradually, Fangshan also saw that they had bad feelings for the first time in their friendship.

Haibo was ordered by his mother to marry the girl next door. Su Li got drunk and finally fell in love with Fangshan. After Haibo got married, life was not happy because of lack of emotional foundation, but he was calm and introverted, and he planned to live like this all his life. Unexpectedly, his wife filed for divorce, and Haibo was hit hard. He resigned from public office and founded an advertising company with Fangshan and Roger.

The three brothers fought side by side, and the advertising company was thriving. After the three brothers developed, they began to swell unconsciously, leading to a fiasco in the stock market and a net loss. Just as the three men were about to make a comeback, Fangshan killed a man with his car, because he was going to marry Su Li. Haibo took the blame for him and went to prison instead of Fangshan.

Haibo went to prison instead of himself, which made Fangshan extremely uneasy. He tried his best to make amends. In order to help Haibo's younger brother Haitao do business, he invested all his property and brought Roger in as a guarantee. As a result, Haitao was cheated, Fangshan lost his own money and Roger's property was seized.

When Roger's house was sealed up, Su Wen, who was pregnant, had a short abortion, and overnight, Roger's family was destroyed. Roger hated Fangshan, which led to all this. After hitting Fangshan, he went away and developed. Friends who used to be as close as flesh and blood parted like this. After suffering, Roger became cold and rose rapidly in the business world. After becoming a rich man, he went home in rags and gave a banquet to treat Haibo, who had just been released from prison. At this time, Fangshan was poor and self-exiled, which made Roger look down on him. After Haibo got out of prison, he started his life again. He treated Fang Shan and Roger, two friends with completely different circumstances and status. With the help of him and Su Li, Fang Shan began to cheer up, wrote the stories of three friends into novels and became a famous writer. With a keen sense of touch, Haibo successfully raised money, became an upstart on the Internet, and regained love. At this time, Roger, because of excessive self-expansion, eventually led to self-destruction: the capital chain was interrupted and went bankrupt overnight.

Roger can't accept the reality of bankruptcy. He arranged a marriage for Haibo with the last sum of money and decided to end his life. Just when he was desperate, Haibo and Fangshan arrived and saved Roger. The three brothers embraced tightly, and a touching friendship began again.
