This documentary film recounts Dr. Sun Lizhe's remarkable experience as a barefoot doctor in rural China and offers a glimpse of China's healthcare condition during and shortly after the Cultural Revolution (1966-1976). Described as "Chinese Dr. Zhivago" in the film, Sun's distinguished life began from his decision to become a "barefoot doctor" when he was an 18-year-old educated youth from Beijing sent down to the countryside. He had since saved numerous lives by performing difficult surgery when emergency situations arose. For example, he once manually removed a placenta from a peasant women's uterus during her placental dystocia. In villages where medical resources were extremely limited, Sun devoted himself to the healthcare of peasants, performing more than 3000 operations in the cave dwellings of Shaanxi province. In 1974 he was selected by Chairman Mao as one of China's five model "educated youths."

The film Morning Sun attempts in the space of a two-hour documentary film to create an inner history of the Great Proletarian Cultural Revolution (c.1964-1976). It provides a multi-perspective view of a tumultuous period as seen through the eyes—and reflected in the hearts and minds—of members of the high-school generation that was born around the time of the founding of the People’s Republic of China in 1949, and that came of age in the 1960s.
