Life for the Major Crime Squad is now severely complicated by the scrutiny of Internal Investigations and a Joint Task Force with the Federal Police into drug importation. The pressure is almost intolerable. Chris Faithful's quick thinking saves her 'cover' when her drug contact Sergio sees her in a bar with Peter and Moon. Despite all their high-tech surveillance methods the Federal Police really blow the Joint Task Force out of the water when they use a helicopter to put a man on board the drug ship. The crooks are tipped off and the drugs disappear! Peter is devastated when his informant Nipper is found dead on the docks. The Joint Task Force is called off and the Majors are left to pick up the threads.
