Water Rats

While investigating a case of illegal medical-waste dumping at a swimming hole, Alex and Mick find themselves searching for a killer when half a body is found among the recovered waste.

Caught off guard while transporting a prison inmate, the Nemesis is ambushed as part of an escape attempt and Jack is taken hostage.

As the resources of the Water Police are mobilised to try and locate Sophie and her two kidnappers, Jack goes off on his own to track down his daughter and her abductors.
