Here is the criminal underground at work: gangland warriors, serial killers, drug dealers and thieves. Melbourne gangland figures Mick Gatto and Andrew 'Benji' Veniamin and their final, fatal encounter; Peter Dupas, the nerdish–looking serial killer who makes your skin crawl; as well as other, lesser–known names – sex–killer Derek Percy who haunted a lost little boy to his death; the man of God who broke the eighth commandment; the murders behind the infamous Arnott's poisoned biscuit extortion.
There are also those whose lives straddle each side of the law: murder barristers; backstreet burglars and back–block magistrates; homicide detectives and community police who go where the worst happens; pensioners who thrive on the theatre of the courtroom; the psychologist who looks into the minds of mass murderers; and sex workers, from streetwalkers, student strippers and fetish models to whip–wielding dominatrixes.
