In a quiet town called "Perfect", Mickey (Kevin Bacon) and his best friend Buster (Fred Ward) spent another peaceful day. The two young people who are full of vigor and vitality feel helpless and troubled by the fact that they are engaged in one job after another with no future and can only make a living in this boring town. Finally, they decided to leave the town of Perfect and start their colorful new life. At this time, the only road leading out of the town collapsed inexplicably, and some ominous signs began to appear. As early as a few weeks ago, a terrorist incident of mysterious disappearance of livestock occurred in the town. At the same time, geology student Rebecca (Finn Carter) discovered that the crustal movement of the town was very abnormal. Now, everyone has finally pieced together these confusing clues. Under everyone's feet, what is it that is stirring in the dark underground?
