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 a terrifying inmate from another wing - a man known simply as Megalodon. Megalodon is determined to get a transfer to Mobeen’s wing so he can confront him about meddling in his business.

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. In the infirmary, he also encounters a doctor, Nida, and there’s an instant spark between her and Mobeen. Nida also suggests she can help Aqsa with a placement for her medical degree, which she is thrilled with. Aqsa also receives some characteristically unhelpful advice from prison chaplain Uncle Shady.

Megalodon throws the prison into a full-blown riot. Mobeen, Nate and Harper split off into different groups. Mobeen is concerned with Dr Nida’s safety, while also keen to keep Memory Stick on side. Uncle Shady ends up with Memory Stick, with both of them desperately trying to evade Megalodon and a wing full of rioting inmates.
