Malcolm Willard has been shot dead from long range, and once again DC Terry Perkins and his brother Ben are in the frame. Perkins is shocked when he turns up at CID to hear that Willard is dead, and that MIT want to interview him. Perkins and DS Ramani De Costa head to Ben's lockup, where they find an empty rifle case. Perkins and De Costa head to the old Perkins house where the abuse took place, and SO19 storm in and arrest Ben, but he is later cleared as the bullet that killed Willard was a different calibre. Supt. Adam Okaro is on trial for drug possession, and DI Neil Manson's wife is his defence barrister. His chances are not looking good though, as the prosecution tears through witnesses PC Steve Hunter and DC Rob Thatcher. DI Manson and PC Andrea Dunbar discover that the DNA on the drugs matches that of Jerome Taylor, and they locate the man who sold Taylor the drugs. Needing an excuse to arrest him so they can get a legitimate DNA sample, Manson goads Taylor into attacking him.
