Ben makes an unprecedented third visit to see his old friends Bill and Bob, elderly twins living in the canyons of Utah. During his previous stays, Ben quickly learned that nothing was quite as it seemed with his eccentric hosts. His home for the week was a cave. He discovered that the brothers were preppers, with several years' worth of supplies hidden in their caves. He also learned that Bob had suffered a stroke and on this visit is saddened to see that his condition has not improved with age. Ben also observes that their paranoia about the outside world has grown. He reassures them that life away from their caves might not be 
as they perceive.
