Who will take home the top prize on NBC's "Get Out Alive With Bear Grylls" finale? Whoever it is, they're not taking the $500,000 grand prize without surviving one last treacherous adventure.
We've got an exclusive sneak peek at the season finale (airs Mon., Aug. 26 at on NBC), above, which features survival expert and host Bear Grylls actually stepping in to nudge the remaining three teams along -- which means literally nudging them straight into a rapid-flowing river where they have to band together and make a human raft to survive.
Watch above and tell us: Would you ever go on a reality show like this? Do you think their lives are really in danger? And, based on the judging criteria of heart, courage, initiative and resolve, who should win?
