How do you conquer a planet? Take away the sun. (It's easier than you think...)

NASA research satellites suddenly go silent as a mysterious dark "spot" appears in front of the sun. A young Kevin Mycroft discovers that the spot is steadily growing in size, threatening to throw the entire earth into permanent darkness. When senior NASA scientists, including Kevin's father, begin intentionally hiding the truth, Kevin convinces his friends to take action on their own. But is there anything they can do to fight the grim fate that awaits the planet?

The origin of the eclipse soon reveals that cold and darkness are not the only enemies lurking in the shadows. And as each fight for survival seems to backfire, Kevin's hopes fade while he questions whether he, or anyone else, can be the hero that the world so desperately needs.
