Richard Rudow is not satisfied with experiencing the Grand Canyon from a lookout tower. He wants to explore inside, and has been doing so for many years. In this film, you follow along as he climbs through dangerously deep slots, repels down waterfalls, and takes a boat out of the canyon because there's no other way out. "You can still find places where no human has ever been," says Richard Rudow, and you're about to see them, too.
