Somebody messed with the wrong mother when they murdered her daughter Angela Hayes (Kathryn Newton). Mildred Hayes (Frances McDormand) will stop at nothing to make sure that her child's killer is caught and after several months of still no arrests, she decides to take drastic action. She forks out for three enormous billboards to go up in her Missouri town with a message to the highly respected Police Sheriff Bill Willoughby (Woody Harrelson). An embarrassed Willoughby visits her to encourage her to take the billboards down, but she's standing firm and will certainly not be intimidated by police involvement - or, indeed, anyone who dares complain about them. She assaults her dentist with his own drill after discovering that he made a complaint and attacks two local high school kids who try to mock her. Even the local vicar is trying to appeal to her sanity at this point, but when she torches the local police station, it becomes clear that she's quickly becoming way out of control.
Tripp doesn't like the small town life that's currently encapsulating his life. He's a senior in high school and can't wait to make a break for a fresh start as soon as possible. Tripp is a great mechanic and starts building his own monster truck but what happens next was beyond belief for the student.
As Tripp works on his car, he discovers a monster living inside his car. Initially scared of the oddity, the human eventually warms to his unlikely new friend and realises that he must've come to the surface after a recent oil drilling accident.
Tripp calls the monster Creatch and notes that he's incredibly intelligent and loves dining on large quantities of fuel. With hunters hot on the heels of Creatch, Tripp must devise a way to protect his new friend.
