The film starts and we see UFOs flying above. Roy sees it up close, and becomes obsessed with finding out what is going, at the expense of his family who think he's gone crazy. He becomes friends with a women he met the night he saw the UFOs, who had her son abducted. They both have visions of a tower, that holds some sort of significance. When they see on TV that near Devils Tower in Wyoming, there has been an evacuation because of a toxic spill, they both realize this is the tower they have been seeing. They travel there, and find an awful lot of mysteries there. What is going on at this tower, that is calling these UFO witnesses there, as well as the military?
