D.C.s Skase, Lines and D.I.Johnson along with Morgan, Pearce and Woods watch a man get into a vasn to do a deal to buy wine that had been hi-jacked. DCI Meadows thinks this arrest of the men in the van has stopped some hi-jacks. Steve is not happy he was left out after feeding Pearce the information. Steve goes and complains to the man who gave him the info. Pearce also gets into trouble because he had got the info from a man he had never seen. Meadows talks to the man watched in the morning who has a license in a false name but he is not prepared to grass on the man they believe was behind the hi-jacks. Monroe argues with Johnson about holding the prisoners. Their mother comes to check on them. Johnson talks to Loxton about running a snout and she apologises. They then go to talk to the snout and find out he had told the other men held about the deal.

Investigating a sawn-off shotgun found in a house fire, Lines is led to Lee Ruddick, a crack dealer. When Lines and Johnson team up to raid him, Ruddick eats the evidence, with fatal consequences.

Johnson stands trial for manslaughter of Lee Ruddick, and allegations of a police cover-up.
