Gordon Buchanan joins the Pazhetnovs, a pioneering family of biologists in snowy Russia as they attempt to rehab grizzly bear cub orphans. Gordon arrives in February when six cubs have just been rescued. They are just five weeks old and each weighs less than a bag of sugar. The group is made up of three pairs of brothers. Working closely with world-renowned bear rehab expert Katya Pazhetnov, Gordon will try to get the cubs back to the wild in just nine months, but without a mother bear everything is stacked against the orphans.

Gordon Buchanan begins training the cubs for their new life in the wilderness; with just ten weeks left before release, little Pasha is still struggling.
