The father of the boy Zhu Yunxiang (played by Bi Xiaohai) passed away, and he had no one to take care of him. Mr. Zhang (played by Jin Shijie), an old school worker from the mainland, was cold on the outside but warm on the inside. He took care of Xiaoxiang for a while before Zhu Yunxiang's biological mother Wu Chunlan (played by Hao Lei) arrived. Wu Chunlan came to Taiwan from the mainland more than ten years ago. After her short dream was shattered, she experienced imprisonment and now lives in a brothel. The stepfather (played by Dai Liren) who makes a living by setting up a stall is filled with hatred and resents Xiaoxiang's arrival. Fortunately, Xiaoxiang met the local gangster Pistol (played by Nadou). Pistol took Xiaoxiang for a ride on a stolen light motorcycle. Although it was improper to cooperate with Pistol to steal and rob elementary school students, it also added some excitement to Xiaoxiang's boring life. Xiaoxiang rarely draws unless necessary, but he also drew a picture for his father and Pistol. The third painting is about Xiaoxiang's brother in his dream, and the brother who has been missing for three years was actually killed by his stepfather. What will Xiaoxiang's fourth painting contain?
