Struggle in Prison [Film and TV Commentary]

Luna is serving a sentence in prison for violent injuries. When the iron door closes behind him, how can he escape unharmed when the iron door reopens and find out the rules of survival to avoid getting into trouble? However, in this prison world where the jungle prevails, the reality seems not as easy as his calculations... The unabashed violence, the realistically presented dim and gloomy prison scenery, and the morally deviant scheming all repeatedly challenge the limits of the audience's tolerance, just like another chapter of "The Prophet".
