Supported by the National Geographic Society, the world's eminent blue whale scientists embark on a revolutionary mission: They'll find, identify, and tag California blue whales, use the DNA samples to confirm the sex of individual whales, then rejoin the massive creatures' stunning migration when they collect at a chimera known as the Costa Rica Dome.
