Prison escape expert Breslin (Stallone) has three students: Zhou Shu (Huang Xiaoming), Luke and Kimbrough. The three of them have very different personalities and very different styles of behavior. During an operation to protect his cousin Ma Yanyu, Zhou Shu and his cousin were captured and sent to a super prison called "Hades". In order to rescue her beloved disciple, Breslin escaped from the "grave" of a prison at sea and then fell into "Hades". This time, the prison was more difficult, the difficulties escalated, and confrontation was imminent. The master and disciple struggled to survive in prison. Outside the prison, his colleague DeRosa (Dave Batista), who is also tracking down the underground prison, fights side by side with them. In the end, with the help of fellow prisoners and team, the three of them fought against several major villains of the artificial intelligence prison chief, and a big battle was about to begin.
