A teenage trapper travels the Upper Columbia tending beaver sets and minding a remote cabin left in his care by an older woodsman. The narrative follows his practiced, watchful movements through riverbanks, ravines, and mountain-bordered wilderness, his quiet reflections on solitude and unknown origins, and his readiness for sudden danger after noticing subtle signs along the shore. Episodes emphasize survival skills, the daily routines of trapping life, and close observation of the natural world that repeatedly tests the boy’s resourcefulness.
