In the windswept, hostile environment of Antarctica, National Geographic's Crittercam* team and Doctors Jerry Kooyman and Paul Ponganis of the Scripps Institution of Oceanography embark on a spectacular adventure of science and survival. Using Crittercam technology, they hitch a ride with the majestic emperor penguin to go places only penguins have gone before - under the massive Ross Ice Shelf.
