Gang member Wesley Meeks is shot, and his dying words in the ambulance are the name of corrupt ex-policeman Ray Moore. Heaton struggles to find evidence linking the victim with his arch enemy, but Lewis's contacts reveal the red scorpion tag sprayed on all of Moore's properties was Wesley's handiwork. Phil's first day back in plain clothes gets off to a bad start, after he and Stuart interview a young joyrider, and follow up a report that he plans to take part in an armed robbery. Manson tells the warring DSs about a temporary switch with a Specialist Crime Directorate, and Phil can't help but gloat when he gets the secondment.
