Dr. Oakley pays a visit to the angriest muskox in the Yukon for a check-up, but he isn't surrendering without a fight. After an exhausting week, Dr. Oakley and the family head off for daughter Sierra's first caribou hunt, a Yukon rite of passage.

Dr. Oakley meets with an Alaskan local whose rescued pets include a reindeer with a hernia and a hungry moose. Michelle and daughter Maya vaccinate lynx kittens, while husband Shane is called away to help fight a wild forest fire.
