3Tim Ross isn't part of the 'cool' crowd. He can't play sport, he's awkward with girls and he has few friends on Insta and Facebook. He hates change and isn't adventurous. So why did he agree to join his elder sister, Danni, on an end-of-school yacht trip off Queensland?
While out at sea, Tim and Danni witness a mystery spacecraft crash into a nearby island. Reluctantly, they investigate.
As they do, United Nations peace-keeping soldiers are deployed to respond. Leading the top-secret unit is former Australian soldier, Brett 'Scorpion' Tanner. His unit includes neo-punk chick 'Jinx' - a feisty Japanese rookie - and former British soldier Leonard 'Snowman' Frost - a violent man of war just as deadly as the blood-crazed aliens the unit is destined to encounter.
Zenith Island is an exclusive Whitsunday resort with five-star facilities and a fantastic fun park. It's here where Tim and Danni, and a group of desperate others, must band together to fight for their lives.
As battles for survival rage, certain things become clear. The aliens aren't the only threat; some people are monsters. And desperate situations can change us all.
