An exhausting battle with a colossal white sturgeon pushes Cyril to the limit, but before the team can tag the eight-foot giant, it gives them a giant-sized shock. A freak wind storm then forces the team to put their white sturgeon quest on hold and head far north into the mountains to help protect the sturgeon's main food source: the pacific salmon. In order to find these migrating warrior fish, that can weigh up to 100 pounds, the guys will have to leave civilization behind and survive in one of the most hostile, rugged mountain environments in the world. Out here, hostile terrain, black bears and grizzly bears lurk around every corner.
