Bertie travels to the remote islands of the Galapagos to find and film three rare animal behaviors seen nowhere else on the Earth, each with an extreme challenge. He will face huge Pacific waves, shark-infested waters, and ultra-fast hunting sea lions on the rugged Galapagos coast, teaching Bertie how these unique animals survive in a rapidly changing world.

Bertie travels to Indonesia to dive amongst some of the most exquisite coral reefs left on Earth, hoping to catch a glimpse of one of the reef's most elusive predators: the mysterious devil ray. His best chance of finding one is to track down a huge annual spectacular, an anchovy feeding frenzy.
