Fifteen individuals must trek from Vancouver Island, British Columbia, to the Arctic Circle for a chance to win $100,000.
Racing against the clock, the contestants are forced to abandon ship amidst raging swells and icy water.
The participants rappel down a cliff and negotiate an elaborate cave system on their way to the Arctic Circle.
The 11 remaining contestants set off on a fishing trawler in turbulent seas; the adventurers search for hidden combinations among kelp beds and octopuses.
The group crosses an iceberg-filled lake; after another participant is removed, the remaining contestants take part in a long-distance rafting event.
Loyalties are tested as the six remaining contestants work together in a bicycle-running race; reluctant llamas add a new twist to a mountain hike.
