The Cold Lands (2013)

When his self-reliant mother dies unexpectedly, Atticus flees deep into the forests surrounding his Catskills home. Wandering the woods in shock, relying on what meager food and shelter he comes across, Atticus' grasp on reality begins to fray. His nerves worn thin, Atticus latches on when he encounters Carter, a scruffy, pot smoking drifter, who lives out of his car and sells handmade necklaces on the festival circuit. A wary alliance forms, with each dependent on the other, but neither sure he is making the right decision.
