Megalodon throws the prison into a full-blown riot as Mobeen, Nate and Harper split off into different groups.

Megalodon is now on Mobeen's wing, and Mobeen must avoid him at all costs - which means trying not to leave his cell.

Mobeen has landed himself in the prison infirmary, where he also has a mission – to befriend a man known as 'Memory Stick' and convince him to hand over vital information.

Mobeen and Nate are just weeks from the end of their sentence, but Mobeen's work as one of the prison's 'listeners' gets him into trouble with an inmate from another wing.
