The second of three episodes in the Galapagos Islands finds host David Yetman hunting large cacti on a desert island. Along the way, he discovers flamingos in the middle of a huge lava lake, ghost crabs (so named for their quick disappearing act) and a variety of plant species endemic to certain islands. Yetman also explores the nesting grounds of sea turtles and finds a unique post office on the island of Floreana where pirates and whalers have used the same wooden container for centuries to leave or take mail depending on its destination. The program also examines the strategies different animal species must employ to cooperate in such close proximity on the islands and how the plant and animal life is impacted by the surrounding climatic forces.
