In Shanghai in 1926, there was singing and dancing in the ten-mile foreign market, but behind the scenes, the torrent of revolution and the haze of reaction were surging. Su Qingyuan, a female doctor who returned from studying abroad, took over her father's Renxin Hospital with the ideal of saving lives and healing the wounded, but she accidentally got involved in the secret operations of the underground organization. She met Lu Jingyuan, a shipping tycoon in Shanghai, a patriotic man who looked gentle and gentle but actually cared about his country.
The oppression of the concession, the pursuit of the warlords, and the betrayal of the traitors closely intertwined the fate of the two. He used the trade routes to transport supplies for the revolution, and she relied on her medical skills to treat progressive people; he protected her from wind and rain, and she held the rear for him. In the troubled times of turbulent mountains and rivers, they are not only comrades fighting side by side, but also lovers who love each other. Faced with the choice between the righteousness of their family and country and the love of their children, they used courage as their sword and love as their shield, looking for light in the darkness, holding on to their faith in the wind and rain, and finally ushered in their dawn and perfection in the depths of spring in Shanghai.
