72 Hours S01E03 - Lana'i, Hawaii

Dropped off in the exotic but treacherous Hawaiian island of Lana'i, three teams composed of three strangers must navigate their way through abandoned beaches, dense brush, steep canyons and scorching flat lands in order to locate a briefcase full of cash in just 72 hours. All they have to accompany them in their quest for $100,000 are their teammates, the clothes on their backs, a GPS and one bottle of water.
