A leading heart surgeon with links to a pharmaceutical company has been executed. Bill McCoy and Charlie Coustos investigate the murder. Maxine and Louise try and save a house full of poor residents who are turfed out of their rented home to make room for Cleary's (Gary Sweet) grand vision of a clean new city. War breaks out between the residents and the police, which culminates in a shoot-up of Central Police Station, which is blamed on the residents. When one of the accused residents—Teresa—goes missing, Louise and Maxine are helped in their search for her by the infamous street person, Lizzie. Lizzie knows how the city ticks and her obsession is getting the world to listen about the evil of Cleary. Lizzie is sure that Teresa has been abducted by Cleary. Bill and Maxine are on opposite sides of the fence. However, they put their differences aside to work on the killing of the surgeon. In the course of the investigation Bill and Maxine work out that the dead surgeon was connected with a research program funded by a corporation headed by Cleary. Maxine soon discovers that Teresa took part in pharmaceutical trials run by the dead surgeon's research division, and then finds the drama revolves around an angelic thirteen year old, Cleary's only child, who is dying of heart failure. Maxine and Bill face death together as they rescue Teresa from Cleary's private health clinic. It is only then that the truth becomes apparent—the heart surgeon was shot because he refused to do a dodgy heart transplant and was about to go public.
