Description：The sequel to "Prison on Fire", veteran prisoner Ah Zheng (played by Chow Yun-fat) had his sentence extended because of a feud with the former section chief (played by Cheung Tsann-Yuk). While serving his sentence, his mother died of illness, his son Liangzai was sent to an orphanage and even resented his father. Ah Zheng wanted to apply to go out to visit his son but was made difficult by the head of the prison guards "Ghost" (played by Elvis Tsui). "Ghost" regarded Daquanlong (played by Chan Song-Yung), the leader of the mainland gang in prison, as a thorn in his side because of his failure to bribe him. He instigated and provoked a rift between the mainland gang and Ah Zheng. A frame-up forced Daquanlong to flee, and Ah Zheng, who was misunderstood as framing Daquanlong, was also forced to flee. On the way, the two met and developed a friendship like "brothers in distress". In the end, Ah Zheng was caught and taken back to prison again. During the riot, Ah Zheng finally got the opportunity to meet "Ghost".
