Nick is on another undercover mission, attempting to bring down several dealers who are involved in a feud. Nick is also attempting to balance his undercover duties, with his regular job in uniform.
It's becoming the Nick show, and in all fairness, he's become a much more interesting, watchable character, you're now waiting for him to crack, rather than fall over a pot hole.
The tensions between Nick and Tony were well explored, with the latter's jealousy being built up over the last few episodes, here it bubbles over.
Great story, but it's so hard to believe that any of the events here could actually be feasible, we're asked to believe that an undercover Nick is working undercover in Sun Hill, whilst continuing uniform duties on the same patch.
Visually great, atmospheric, and everyone certainly looked the part.
Hard to swallow, but hard to argue that it was a cracking watch, 8/10 .
