This is one of the more unusual films about a nuclear holocaust, nearly introspective in its focus on a handful of people in Sydney's world-famous opera house, finding ways to pass the time until the morning brings more news. The setting is New Year's Eve (in the middle of summer here), and some intimation of the immediate future surfaces in the form of reports on a major crisis in Europe and the aftermath of demonstrations against U.S. nuclear ships at harbor in Sydney. Sharon (Cassandra Delaney) and Eva (Saskia Post) are young teen roommates who are more interested in their own personal relationships than what is happening in distant Europe, and after meeting at the opera house where Sharon works, they are ready to go off to a New Year's party together. But before they can leave, a radio broadcast announces that nuclear bombs have been dropped in Europe and North America and also on U.S. targets in Australia. The announcer requests that people remain where they are, and the two shocked teenagers are at a loss as to how to cope. They are soon joined by an American soldier gone AWOL and a custodian who was busy working after the end of the evening's concert. The four isolated people explore the empty building, engage in conversation just to fill the time, and even distract themselves with a game of strip poker -- anything to avoid facing the possibility that this may be the last night of their lives.
