Anthony LaPaglia narrates this look at life in one of the world's most inhospitable places, Death Valley. Included: Devil's Hole pupfish, which live in waters deep beneath the desert's surface and whose numbers are dwindling; kangaroo rats; black-tailed jackrabbits; and bighorn sheep, which have a nine-stage digestive system that enables them to eat even the harshest of desert plants; and the desert tortoise, which eats enough food for a year---and mates---during just two weeks each spring.
