In the 1970s America, Jack, a hitchhiker, borrows a truck from a truck driver named Stu. They travel together because they share the same destination, but Stu's behavior becomes increasingly unsettling. Stu, acting as if this is the first time he has done this, begins to toy with Jack. However, at a certain point, the dynamic between the two completely reverses... and Stu realizes that Jack had been hunting him from the very beginning.
