At the age of 10, Australian-born Andi Gibson had what she describes as a close encounter with a flying saucer. 17 years later, an airborne extra-terrestrial armada launches a nation-wide assault on Andi’s home country and for unspecified reasons, also kidnaps her mother. To add to the debacle, it seems the other nations of the world are far too insulted by their exclusion from the attack to come to Australia’s aid. Now it’s up to Andi, her hypochondriac brother Elliot, retired boxer cousin Keith and documentary filmmaker friend Cam to stop the attack and rescue Andi’s mum. Bloody hell, this is gonna be a long night.
