 He exploits the resources of a declining gangster, Ryan (Godfrey Quigley), to take over the dominant crime syndicate Scot-Yanks, controlled by the equally ruthless and manipulative Lennox (Timothy West).The key to Hogarth's success is knowledge of a murder arranged by Lennox, of which there is a crucial witness, Ackerman (Donald Burton), a one-time private eye who has been blackmailed into working for Scot-Yanks and bitterly resents Lennox.The eight-part serial was widely condemned at the time for its amorality and violence.
