Tooling across the American southwest in their giant Winnebago, Max and his nephew, Owen, seem harmless enough, the actorly old fellow spouting Shakespeare like a faucet while his young charge trots him through select tourist destinations along the road. But appearances, as you might imagine, can be deceiving.Old Max is actually a master thief, and young Owen's 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.
