After a night out on the town, Parker Graves returns home to life-threatening danger. The science reporter for the local newspaper barely misses a bear trap sitting on his doorstep. Then, the object transforms into what looks like a bowling ball and rolls off into the night all by itself. He begins to obsess over the question—Who put the trap there? And why? The following day, there is strange news floating around at the newspaper office. Someone with limitless funds is buying up hundreds of homes and businesses, only to close them up and tear them down. 

Forestry student Jerry Conklin is fly-fishing when something huge lands on his car, crushing it into the earth. It looks like a big black box-about fifty feet high and two hundred feet long-and the object stirs up quite a commotion among the townspeople of Lone Pine, Minnesota. One of them even shoots at it-and quickly pays for it with his life.
