When a mysterious force knocks the Moon out of its orbit and sends it on a collision course with Earth, humanity has barely a few weeks before the cataclysm. A disgraced former astronaut, a NASA executive and a conspiracy theorist who discovered the threat join forces in a desperate mission to divert the satellite. What they find as they draw near defies everything they believed they knew about the Moon's origin. Roland Emmerich takes disaster cinema to a delirious extreme, with large-scale destruction and an outlandish science-fiction twist.
