Each year, 500,000 Americans visit Costa Rica to explore some of the world's most amazing and environmentally significant wilderness preserves. Last year alone, more than 50 visitors had to be rescued by the Red Cross. Bear sets out on an incredible jungle adventure as he parachutes into the rain forest of Costa Rica's Osa Peninsula to demonstrate how someone lost in the jungle can make it out alive. His journey takes him up 100-foot trees and down waterfalls that descend more than 120 feet. He encounters snakes, mosquitoes and dangerous river currents, while searching for food and water and setting up camp.
