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.

The paths of the Major Crime Squad and the Dealers Squad meet when the Dealers come across a stolen watch linked to the aggravated burglaries. Resources stretched to the limit, the Majors also take over the interrogation of Joanna, a young offender pinched by the Dealers. In Forensic, Ian and Carol begin the difficult task of identifying unusual dirt samples found at the scene of the last aggravated burglary. Inspector Lew Murdoch, an ex toe-cutter, arrives to head up the Majors and appears to be a nine to five man with an 'attitude' problem. Squad morale goes into decline. A raid planned behind Murdoch's back turns into a fiasco. Complaints roll in and the Inspector's wrath descends on the squad and particularly on Snr.Sgt.Moon.

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.
