"72 Hours'' takes a page from the ubiquitous survival programs on TV and adds a competitive twist. Each episode features three teams made up of three strangers given a chance to win $100,000, but the challenge presented is a stiff one. The teams are dropped by helicopter into a remote wilderness location, and each of them is armed with just one bottle of water and a GPS tracking device. The ultimate goal, beyond literally surviving the contest, is locating a hidden briefcase full of the cash within three days. Along the way, the first team -- all three members have to find the briefcase together -- to display the best strategy, limit infighting, and overcome the elements and physical challenges such as hunger and thirst, will discover newfound riches. Tasmania, Fiji, the Hawaiian islands, the Rocky Mountains and New Zealand are among the series' locations, and Brandon Johnson is the host.
