When a man brutally murders the surgeon who has just changed his face, the team find themselves in the middle of a double murder investigation as they also investigate the shooting of a retired police officer, known by Langton at a dealer's den on a seedy estate, which links into one of the FBI's Ten Most Wanted, a dealer who vanished over ten years ago.

Whilst Roache admits to shooting Frank in a panic, he denies killing Danny. Middle-class dropout and user Julian D'Anton's prints are on Danny's car, though Langton considers him too small-time to be a murderer. From a photograph, Travis identifies Julia's ex-husband as an international criminal and asks Sam Power to contact the FBI for details of his crimes in America.

A fraud inspector visits Langton for Julius' whereabouts, but this proves to be Alexander Fitzpatrick in disguise, who stole all the Drop Dead after finding them in Danny's car. Fitzpatrick retrieves his haul after killing Julius's wife, but a vital clue is provided when DNA found at the crack den matches that at Helga's farmhouse.
