Neighbours. Everybody needs good neighbours, goes the traditional Australian folk song.
Well, here the neighbours - a sort of pan-Asiatic invasion force known as The Coalition - aren't good. They're very bad indeed.
After launching an airborne attack on Oz, they've interned the locals (a shot to the head deters any would-be rebels) and set about plundering the country's natural resources.
The town of Wirrawee is among the key strategic towns acting as a bridgehead for the occupying force...but the invaders don't count on a handful of locals fighting back.
A gang of teens led by ballsy chick Ellie (Caitlin Stasey) marshall themselves into a guerrilla force and use whatever comes to hand - lawnmowers, garbage trucks, oil tankers - to hinder the enemy.
