Tom and Nancy Oar are scrambling to get through the last of their winter works when a surprise call comes in from their family that will force them to make a difficult decision. In the Ruby Valley, Rich passes on some of his lion hunting knowledge to a greenhorn.

Charlie continues to struggle with his injury, while racing the change in seasons to secure some final furs, and after a highly successful season, Marty bear proofs his cabin and prepares to head home to Two Rivers.
