Jailbreak expert Breslin (played by Stallone) has three students: Zhou Shu (played by Huang Xiaoming), Luke and Kimbro. The three have very different personalities and styles of doing things. In an operation to protect his cousin Ma Yusheng, Zhou Shu and his cousin were captured together in a super prison called "Hades". In order to rescue his beloved apprentice, Breslin escaped from the sea prison "Grave" and then fell into "Hades". This time the prison is more difficult, the difficulties are upgraded, and the confrontation is imminent. The master and his apprentice struggled to save their lives in prison. Outside the prison, De Rosa (played by Dave Bautista), who is also tracking down this underground prison, fights side by side with them. In the end, with the help of their cellmates and the team, the three fought a desperate battle with the artificial intelligence warden and several villains, and a big battle is about to begin.
