In this feature documentary, husband-and-wife team Karsten Heuer and Leanne Allison (Being Caribou), along with their 2-year-old son and dog, retrace the literary footsteps of Canadian writer Farley Mowat. They canoe east from Calgary towards the Prairies (the geography of Farley's Born Naked and Owls in the Family) and then traverse the same paths that Mowat took more than 60 years earlier in Never Cry Wolf and People of the Deer. Their epic 5,000 km journey—trekking, sailing, portaging and paddling—ends in the Maritimes, at Mowat's Nova Scotia summer home.
