Bill and Bob Stone are twin brothers aged 72 who fled their adrenaline-junkie pasts for a tough subsistence lifestyle hidden away in Americaʼs Wild West. In this unforgiving landscape, even with one of them recovering from a stroke, they carve out an existence and fight the challenges associated with growing old. Ben joins these canyon-dwelling renegades in their remote, isolated home, deep inside some of the worldʼs most striking and wild terrain.
