From the cold Arctic waters to the warm Baja California lagoons, the longest migration on Earth is made by the gray whale. The creatures' journey spans more than 5,000 miles. Audience members are taken under the ocean's waves to view these underwater giants. Each November on tiny Christmas Island in the Indian Ocean, a migration takes place. Millions of red crabs make a dangerous journey from the forests to the shores to mate and spawn.
Audience members join the creatures as they march to their destination.
Spectators are taken on a sort of safari for the next adventure. The zebras lead wildebeests, antelope and gazelles from the dry plains of East Africa to the tall grass and waters of the north. This trip of 500 miles takes viewers through crocodile-filled rivers and other obstacles that these magnificent animals must overcome. Finally, humankind is featured on a journey. The Hadzabe tribe of East Africa still follows a hunting and gathering life using tools developed during the Stone Age.
