For some 100 million years, the flora and fauna on the island of Madagascar have evolved, completely independent of the rest of the world. Steve travels to this unique biosphere off the coast of Africa to leap with lemurs - a rare, ancient species of primate. Steve's adventure on a bicycle begins on Madagascar's south coast and as he travels north he encounters many of the Malagasy species, including the smallest and largest lemur. Steve also discovers other unique wildlife including snakes and chameleons, along with other very close encounters.
