So what I got from the trailer is that there is a signal. No, THE SIGNAL. And a kid can hear it. He's one of the few people that can. And Fishburne doesn't exactly know what it means. But he knows enough to be in an environmental suit while interviewing the kid. Also, there maybe some dragonball type psionics involved.
Actually, I like this kind of ambiguous type of science fiction sometimes. But they aren't for everyone. Look for it in theaters this June 2014.
