Tom has been branded a traitor and has disappeared, while Harry is in hospital, seriously wounded, and there is dissension in the ranks. Danny and Zoe seek to clear Tom's name despite the fact he appears guilty and may even be dead. Will Tom, missing since shooting Harry, re-emerge to prove himself an innocent victim of a set-up?

If his track record and the reputation that precedes him are anything to go by, there are going to be plenty of fireworks.
