Hardy realises that his loyalty towards his cousin may be misjudged after he and Valentine are confronted with a gun as they break up a brawl between two major gangs. Shand manages to convince Jordan Tomlin to gather information on his behalf, and it's not long before the gun used in the shooting at the 222 club is discovered. When they discover gang leader Mitchell Simmons was responsible for the shooting, they realise that they have little time to stop him before he attempts to wipe out the rival leader who ordered the hit on his girlfriend. Meanwhile, one of the witnesses from the first shooting is found dead in the boot of her car, and Harman suspects her husband may be responsible.
