Last of the Giants (2021) : 1x4

Time is running out, and the team must return to the Fraser River to find and tag the 300-pound giant white sturgeon they are looking for. But first, they have to find their way out of the remote wilderness to deliver their salmon samples. Stranded by severe weather, they'll need to survive brutal rapids, rappel down terrifying cliffs, climb a massive glacier, and hike across rugged mountains if they want to succeed. And with a massive prehistoric fish finally on the line, the guys are in for a white-knuckled end to their northern mission.
