Tooling across the American southwest in their giant Winnebago is Max, a master thief, and his nephew Owen, whose summer vacation is his careful apprenticeship in a life of crime. Pulling heists is scary enough, but ominous signs point to the alarming fact that The Subtractors are on their tail, criminal bogeymen who stop at nothing to steal from other thieves. The road trip soon turns into a chase, by turns comic and horrifying. The most disturbing twist: Owen''s slow realization that the person he loves most in the world is the one who can do him the most harm.
