Indonesian genre maestro Joko Anwar made his mark with Satan’s Slaves and Impetigore. Now he’s back, combining martial arts, extreme violence, and comedy in what may be the wildest prison movie ever made.

After his editor is found murdered, journalist Dimas is sent to a maximum-security prison. There, he joins forces with Anggoro and his gang, the only inmates willing to stand up to the sadistic head guard’s reign of terror. But then someone starts killing off the prison’s most dangerous inmates.
