Neal McBride is a Glasgow cop who likes to go undercover - the rest of the police wish he would stay there. When he arrests a politician he gets reassigned to where they used to send criminals: Australia. Lancelot Cooper is a Sydney cop but a country boy at heart; he is as trusting as McBride is suspicious. The two are partners on a case where death, deception and betrayal propels them into a desperate fight for survival.

Set in Australia, against the backdrop of World War II, this epic miniseries centers on the religiously divided town of St. Helens and the innocent romance between a pair of star-crossed teenagers that threatens to tear it apart.

The world has finally managed to blow itself up and only Australia has been spared from nuclear destruction and a gigantic wave of radiation is floating in on the breezes. One American sub located in the Pacific has survived and is met with disdain by the Australians. The calculations of Australia's most renowned scientist says the country is doomed. However, one of his rivals says that he is wrong. He believes that a 1000 people can be relocated to the northern hemisphere, where his assumptions indicate the radiation levels may be lower. The American Captain is asked to take a mission to the north to determine which scientist is right.
