The ultimate test of survival...
When the cast and crew of science-themed reality TV show SeaLife land on picturesque, unexplored Henders Island it's a ratings bonanza. But they're blissfully unaware that the decisions they make there will shape the fate of mankind... if they can only survive.
For they quickly discover that the island is seething with danger. It's a fragment of a lost continent, with an ecosystem unlike anything they've seen before: a host of vicious and exotic predators, who live in a lightning-fast blur of kill or be killed. If even the smallest bug ever made it off Henders Island, life on earth as we know it might very quickly cease to exist.
But just when it seems the stakes couldn't get any higher, the scientists make a surprise discovery that changes everything...
