Cyril et son équipe doivent vite retourner sur le fleuve Fraser pour capturer un véritable esturgeon géant de plus de 150 kilos.
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.
Im Dienste der Forschung trotzen Cyril und sein Team einem Sturm, durchqueren reißende Stromschnellen und erklimmen Fels- und Gletscherwände. Sie wollen wissen, warum die Lachsbestände schrumpfen. (Text: Sky)
