This film tells the story of three orphans who depend on each other for survival. The two brothers made great efforts to help Bai Xiaoting treat congenital heart disease. The purpose of this drama is to popularize the public's concept of organ donation. Organ donation is not to disassemble oneself, but to give one's unfulfilled dreams to those in need. This is a kind of love for society and a great love for fellow human beings. It also reflects the love of life and the contribution to society of the post-95s and even the post-00s. At the same time, it also warns young people not to participate in illegal activities and improve their traffic safety awareness.
