The opening episode traces the events that have created the unique landforms and ecology of South America. Originally part of the supercontinent Gondwana, it broke away around 100 million years ago and became an island. At that time, it was dominated by reptiles and strange plants similar to the araucarias and tree ferns of Chile's Valdivian forests.

The second programme shows how life along the Amazon River is dominated by the annual cycle of floods. In the dry season, female giant river turtles gather on exposed sand banks to lay their eggs. As broad reaches of river are cut off by sandbars, caimans and egrets take advantage of the bounty of fish trapped in shallow lagoons. Underwater infrared cameras film scavenging candiru and an electric eel hunting.
