At the age of 10, Brisbanite Andi Gibson had what she describes as a close encounter with a flying saucer. Naturally, everyone assumed she was bonkers. That is, until the aliens returned 17 years later, but this time they have an entire armada at their back and total domination on their minds. With the military outmatched in every way, it's up to Andi, her hypochondriac brother Elliot, retired boxer cousin Keith and documentary filmmaker friend Cam to battle car-chasing spaceships, kung-fu aliens and giant killer robots. Bloody hell, this is gonna be a long night!
