Five teenagers find themselves on board a spaceship. The alien beings who brought them there say they want to save the Earth. But why do they need the five humans? And what will happen if they don't cooperate?

In a remote Arctic research base, scientists find worms alive after thousands of years in the ice. Taylor and Miles, visiting science students, help with the scientists' work - until they discover something else that has survived the freeze. Something that could threaten the whole planet. They need to act fast - and a storm is moving in.
