Cheng Yong (Xú Zhēng), an ordinary middle-aged man, runs a health care shop, but he is frustrated and divorced. The arrival of the uninvited guest Lu Benefiting (Eric Wang) opened up a new business of purchasing medicines in India. Although there were many difficulties, he found business opportunities on this road of purchasing medicines, and started out of control as the exclusive agent of Indian generic medicines for treating CML.

While making money, he also met several patients and their families. Si Hui (Tan Zhuo), who was forced to be a dancer to save her daughter, Pastor Liu (Yang Xinming), who speaks fluent English as a priest, and "Huang Mao" (Zhang Yu), who has a violent temper. Several people started a business together, and their profits doubled and they were also in danger.

Cheng Yong"s former brother-in-law Cao police officer (Zhou Yiwei) was ordered to investigate the origin of generic drugs, and counterfeit drug dealer Zhang Changlin (Yanhui Wang) and Swiss real medicine representative (Li Naiwen) were also eyeing it, and the business gradually turned into a tug-of-war about redemption. This film is adapted from the real story of Lu Yong, a patient with chronic myelogenous leukemia, purchasing anticancer drugs on his behalf.
