Based on the 'American Short Story Masterpiece' by David Quammen, 'Walking Out' tracks fourteen-year-old David’s (Josh Wiggins) annual visit to rural Montana to see his brooding, off-the-grid father, Cal (Matt Bomer). Separated from the comforts of home, David is reluctant and resentful as Cal plans the boy’s first big game hunt.
As the pair ascend into the wilderness, Cal tried to connect with David by recounting the story of his own first kill, on his last hunting trip with his now long-dead father (Bill Pullman). After their trip is disrupted by a chance encounter with a grizzly bear, a wounded Cal realises they must both rely on David’s strength and resilience to survive.
