In the autumn of the 16th year of the Republic of China, the French Concession in Shanghai. Shen Qingyi, a female doctor who returned from studying in Germany, opened a Western medicine clinic in the concession. One rainy night, Lu Chenzhou, the most powerful young warlord on the beach, suffered a gunshot wound and fell in front of her clinic. Shen Qingyi rescued him, but she didn't know that the rescue would involve her in warlord battles, gang strife and an involuntary love affair. He needs her medical skills to save his life, and she needs his power to protect the clinic. A contract bound the two people together. He moves step by step amidst the smoke and intrigues, while she sticks to the medical path between the scalpel and the medicine box. Until the truth emerged - the shooting was not an accident, and her identity was far from being as simple as an ordinary doctor.
