Jack, Mike and Trip were ripped from their loved ones and thrown into a dangerous world they know nothing about, relentlessly pursued by Night Runners, Zombies and terrifying new creatures known only as Whistlers.
Like their own worlds, civilization has collapsed and danger lurks around every corner. The trio can do nothing but march forward and attempt to find some answers - some way to escape from the nightmare. Seeking only to return to their families, they must navigate through the unknown.
Everything seems to be converging Atlantis. Will Jack, Mike and Trip find what they are looking for in the city? Or will they meet an end that none of them were prepared for?
