In the near future, Earth is falling to a catastrophic alien invasion: giant beetle-like creatures emerge without warning from spatio-temporal rifts, wipe out resistant in a certain zone, then seal it behind a completely impenetrable barrier. Entire sections of the planet have already been lost forever. With conventional weaponry powerless, the USA authorise a program that will turn five teenagers into pure geniuses. Will the test subjects find a defence, though - or will they become out of control themselves?
