Sociological researcher Lu Xinquan came to a health care center in Mogan Mountain to conduct social and psychological investigation and research, and met Liu Dafu, a veteran who had participated in the self-defense counterattack that year. Liu Dafu received a special pension arrangement from the government because of his meritorious service in defending the country and was admitted to a nursing home. However, he was withdrawn, lived alone, talked little, was preoccupied, and was depressed. He always kept his distance from other elderly people, which gave Director Xiao of the nursing home a headache. The arrival of Lu Xinquan gave Dean Xiao a glimmer of hope. She hoped that Xinquan would try to open the old man's heart and let him return to a happy life in the sun. However, years of ice cannot be melted so easily. What did the old man go through back then that caused such a heavy impact on the next few decades? How can young Lu Xinquan break through this last line of defense and bring old Liu Dafu out of the haze?
