A calculating serial killer, who 'trophies' the faces of his victims, is targeting Londoners and committing the most gruesome of murders. With each new atrocity, the public and the police are getting more desperate for results. Under enormous pressure, DCI Jack Hawksworth and his team begin their investigation and soon find it taking them into the murky world of illegal immigrants and human organ trading. But when the murderer strikes closer to home than Jack could ever have imagined possible, the case becomes a personal crusade - and a race against time.
