In the chaotic remains after the Police Club bombing, over the grim task of sorting through the pieces, Ian and Jock are forced to work together. With the death toll mounting, the only leads come from within the police force itself. One is the shell shocked young constable who is Jock's only eye witness. The other is a disgruntled policeman who may well have set off the bomb. The police find themselves doing what they dread most, investigating one of their own.

In a raid on the stolen car garage, Nick - one of the bombers - is caught in their net. A relentless round of interrogations go on into the night. Nick keeps a very low profile. He manages to wriggle free, unsuspected. There's not a shred of evidence to connect him. He walks into the night, laughing at the police.

Pursuing another line in the bombing investigation, the team raid known drug dealers with the hope of shaking out much needed information. One raid goes wrong when Lochie, the Senior Sergeant, is nearly shot by a terrified dealer. During questioning, it's discovered the frightened man was robbed - and his young sister assaulted - by some very dangerous men. It all points to the bombers but the dealer will not talk - no matter what. He's scared to death of the men. It's a frustrating dead end for the team.

The final curtain. The investigation team know they are dealing with mad dogs who are unlikely to come in quietly. The raid, then the interrogations have to come off with lightning precision as they race against time to charge the bombers.

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.

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.

Pressure mounts on the Majors when they are forced to run their own surveillance on Flannagan, a prime suspect. Peter Faithful confirms the importation of drugs via Nipper, his informant on the docks.

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.
