2026• 52 minG

Synopsis

Alaskan volcanoes have repeatedly erupted, forcing salmon to adapt and navigate perilous environments, including sulphurous waters and predators, to survive.

Synopsis

Time and again, over the centuries, Alaskan volcanoes have erupted and poisoned the environment. Scientists have only just begun to piece together what might have happened nearly 2,000 years ago, when one race of salmon faced the death of their natal river and were forced back to the open ocean - on an extraordinary adventure. Navigating between the sulphurous waters, bears, sharks and eagles, the fish escaped the earth's wrath to give birth to descendants that continue their pioneering journey to the heart of an active volcano.
