'March of the Penguins' Traces Steps of Emperor Penguins

The documentary 'March of the Penguins' traces the steps of emperor penguins during the course of a year, as they undergo repeated, harrowing marches back and forth across the Antarctic icescape. In the midst of these journeys, if successful, the penguins will pair off, mate, and raise their young, all in the darkest, coldest place on earth.
