The Major Crime Squad's investigation of a series of aggravated burglaries leads to an unexpected discovery. The Major Crime Squad is understaffed and leaderless. Sergeant Peter Faithful and his crew struggle to deal with existing investigations when the fourth in a series of aggravated burglaries on 'soft targets', the elderly well-to-do, takes place. The victims of this latest outrage, Betty and James Arthur, have been viciously beaten and terrorised in their own home. The thieves know their targets and take only select valuable items. Tension in the Squad rises as newly appointed Senior Sergeant Adrian Moon follows orders to pull the Majors into line. His manner does nothing to endear him to Faithful and the crew when he turns a key investigation over to the Armed Robbery Squad.

Russell Howie, from the Fraud Squad, is recruited by Murdoch to join Major Crime. Shock waves roll through the Major Crime Squad when a second aggravated burglary takes place on the same elderly victims; Betty Arthur is viciously raped and her husband James beaten for six valuable stamps.

After a tip-off, Murdoch authorises the Majors to raid a warehouse where they score a huge cache of stolen goods. Following the warehouse raid, Howie is the target of complaints of sexual assault by Lindy.

Meanwhile Faithful is overheard by internal affairs, making a deal with a criminal and the Majors suffer a staggering blow when crime victim James Arthur is found dead in his home. What appears to be murder is proven by the forensic team to be Arthur's macabre and tragic attempt for revenge.

Conflict spreads through police headquarters when the Majors and Drug Squad investigations begin to cross-over.

Jock Brennan announces that the Major Crime Squad is to be disbanded. As the bitterly disappointed detectives plan to track down the last crook, Ian uncovers the mystery that has plagued forensic from the first burglary.
