Idris, Kiki, Sarah, and Cody are known as The Stonewood Survivors. After launching a comm-satellite to serve as a beacon for others lost on the Island, they're hailed as heroes.

But heroes' work never ends.

Core to their mission of survival is uncovering information about the founder of the shadowy corporation, Vindertech. This they know: Dr. Vinderman is the mastermind behind a host of wonder weapons that includes Ray the Robot and, more importantly, humanity's last hope for survival, the Storm Shields. What they don't know is whether Dr. Vinderman is working for or against them.

To get to the truth, they must paraglide over herds of ravenous Husks and Mist Monsters, land on the roof of Vindertech Research Labs, save the supercomputer servers housed there, and discover Dr. Vinderman's location.

Nothing happens as planned, and soon they are trapped in a deadly game of hide and seek. Hunted by the maniacal sniper known as Teddy Bear, they enter storm-wracked Plankerton where, if they're not slaughtered by mutant fiends, they just might save the world--assuming they don't kill each other first!
