Terravex Oil is in the midst of a fracking operation in North Dakota, overseen by CEO Reece Tenneson and geologist Jim Dowd. The operation releases three subterranean creatures from an underground water system and destroys the drilling rig. Two are captured by Terravex, but one of them escapes. Meanwhile, high school senior Tripp Coley has taken up a job at a junkyard, where he builds a pickup truck in hopes of being able to leave his town. The truck doesn't have a working drivetrain. One night, Tripp encounters the escaped creature in the junkyard and captures it, but the creature escapes before he can seek authorities.
