Fascinating footage, our journey begins in Alaska's Katmai National Park, both inhospitable and beautiful. We observe brown bears as they hunt salmon, track the rare glacier bear, and then continue south to British Columbia on our hunt for the rare Kermode bear, also called ghost bear or spirit bear.

During the night, Sam Gruber's team of biologists has captured a young tiger shark, a perfect candidate for their scientific research.

Sam Gruber's team of biologists capture, tag and release a juvenile tiger shark. Then they track it electronically into the mangroves, an ideal location for their research.
