Wire in the Blood (2002)

Season 4: Episode 1

When a rapist who was convicted on Tony's evidence is released Tony appears to be discredited. To make matters worse Carol has left for South Africa without even saying goodbye to him. He offers his help to her successor, Alex, another female officer, when a number of young women are found dead, their bodies buried in fields. Tony relates this to a sado-masochistic Internet site used by the murderer to lure his victims to their fate by playing, and then preying, on their sexual fantasies.
