In Moscow, four young people, each with different goals, must work together to survive after an alien race has invaded Earth for power and minerals. The aliens themselves consist of a floating monstrous head, surrounded by four, constantly-revolving, spiny arms, which allow it to fly. However, they are protected by a shield that renders them completely invisible to humans. On top of this, they can vaporize any organic matter they touch, and can manipulate things with a controlled lightning bolt. It is discovered, however, that they are incapable of detecting things without line of sight (in other words, they cannot see through glass), and their invisible shields can be disabled with strong rays of microwave radiation. Being the only people in the world with this information, the four teenagers must find a way to safely get to a Russian military submarine that is rumored to be in the area.
