In the toughest competition show ever attempted, eight teams of elite athletes embark on a harrowing journey across the unforgiving Alaskan wilderness. But with no food or shelter, they must fend and survive off the unwelcoming land. Over the course of six different race legs, 46 days and 300 square miles, teams will traverse through some of the harshest and most extraordinary landscapes in the world, from sprawling mountain ranges to massive prehistoric glaciers and never-ending suffocating rainforests. Teams will be tested like never before, enduring physical pain and challenging their mental fortitude. They will scrape and claw, forge alliances, and backstab their way to claim a spot in the finale and a chance to win a life-changing $500K prize. That is, if they can survive the hostile land… and each other.
