Jock Brennan, Inspector of the Major Crime Squad, is pursuing a vicious armed robber who has stolen police service pistols. Ian Cochrane, public servant and scientist, is in charge of collecting the forensic evidence. These two men argue heatedly at the crime scene. Forensic is not Jock's priority. His attempt to dismiss Ian from the scene results in a stand up fight. In court, Ian is cross examined relentlessly. He's stunned at the attack on his personal integrity. Jock is stunned when they actually win the case. The two men's antagonism comes to an abrupt halt when the Police Club's annual party is bombed.

The last vestiges of Laz's undercover persona are blown when Jock orders him to start acting like a detective. He can no longer work the streets without risking his life from the criminals he once lived amongst. It's a terrible loss of identity which leads to a violent outburst. Defending his Senior Sergeant, he assaults a member of the public. This brings him under the cold hard scrutiny of the Internal Investigations. Before it's over, Laz could be charged with a criminal offence.

Knowing that they are facing very heavy villains, Jock allows a member of the crack Special Operations Group to be assigned to the bombing investigation team. Although Blazo is the epitome of a black suited 'headkicker', it soon becomes clear that Blazo is not a thug but a thinking policeman. The small boy in Ian falls 'helplessly in love' with the Special Operations cowboys. Bags of high explosives are recovered from a river - a sure indication that bombers maybe getting ready to do a runner - getting rid of the evidenc. Time may be running out for the investigation if the bombers decide to head out of the state.

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.

The Majors and the Bureau of Criminal Intelligence lock horns over an informant.

Frustration mounts for the Majors when another aggravated burglary occurs.
