World record holder Colin O’Brady hosts the Jones from Orange County, California, and the Williams from Phoenix, Arizona, on a formidable three-day, 16-mile expedition through one of the most remote parts of the country. Floyd Jones wants to learn a better way to communicate with his young sons. The Williams want their daughters to strengthen their strained relationship. The families will compete in survival challenges of shelter, food, and knot tying, before racing into the wilderness. Parents and children alike will be tested as they face a polar plunge into an alpine lake, navigating wild terrain on horseback, and a demanding 10,500-foot pass through the mountains. Which family will pass nature’s test and claim the $10,000 prize?
