Refugees from an overtaken planet hide on earth from their invaders, who now hunt them here. The refugees must be killed in numerical order, this is the story of number four. A teenager who is always moving, always hiding finds a place he feels at home. But the aliens that want him dead are not far behind.
What did I think? I enjoyed it. It was different, not a remake, not a retelling of the same old story with a slightly different angle. Pettyfer did a good job of playing a teenager who is tired of being told what to do, and rebelling in his own way. I recommend!
