Emotions run high as Michelle prepares for her first-born to leave the nest while the case of a tarred eagle proves almost too much to handle.

Dr. Oakley�۪s job is proving to be dangerous, as a few of her patients strike back at her.

Each spring Dr Oakley visits Alaska to help with birthing season. This year she visits a reindeer farm, a moose rescue and a conservation center.

Spring has just arrived in the Yukon Territory and for Doctor Michelle Oakley that means long days, helping a caribou fight the heat; and even longer nights helping a weak cow deliver an oversized calf; second chances, removing an infected eye to save a horse; and new lives, bringing five French bulldog puppies into the world.

Michelle pulls out all the stops to save a baby moose from certain death, and Sierra goes on a hunt to save an injured bald eagle.
