Ordinary white-collar Li Xinyue spent tens of millions of dollars to buy the painting "Baby" by the great painter Chu Hongfei. This strange behavior attracted the attention of the police and was tracked like a shadow by undercover policeman Jin Xiaotian. The two of them got on the live broadcast travel RV of Chu Zhihan, the entrepreneurial project of Chu Hongfei's son, and drove to Shangri-La, Xinyue's hometown that she missed and feared. During the picturesque journey, Li Xinyue and Jin Xiaotian, who had always protected her, had a mutual affection, but Jin Xiaotian could not express his feelings because of his undercover identity. In order to protect the original painting "Baby", Xinyue was kidnapped by a drug cartel, and Jin Xiaotian rescued her alone. Under the test of life and death, Jin Xiaotian finally expressed his feelings to Xinyue, and the two vowed to live and die together. When all the ugliness co-directed by the drug cartel and Chu Hongfei was exposed in the sunshine of Shangri-La, Xinyue sought justice for her painter father. And Xiaotian also successfully completed the task and grew into an excellent people's policeman.
