Grandpa answered the call to support border regions and entered Tibet, father led villagers to grow grapes to lift themselves out of poverty, and Li Mingyu gave up a high salary in Shanghai to return home and use new media to sell his hometown's wine to the world. He faces a factory director competition with cultivation expert Dengba, as well as Zhuoma's emotional dilemma between signing with an internet celebrity agency and staying in her hometown. Drought strikes and the crisis of adulteration in outside grapes follow one after another. With the support of the Party, the government, and eastern-western cooperation assistance forces, and inspired by the Red Army's honest story of the 'cattle pen branch committee', the two turn from rivals into comrades-in-arms. Three years later, 'Gorge Red Heart' wins an international gold award, and the unanimously elected factory director, together with the villagers, lets the world taste the loyal heart of the children of the plateau on this hot land.
