- On a quest to find out what happened to his missing brother, a scientist, his nephew and their mountain guide discover a fantastic and dangerous lost world in the center of the earth.
- Meet Dr. Hazel Barton and Nancy Aulenbach. These women are compelled to push their limits in hostile environments. They are cavers who risk fatal danger for the thrill of discovery. Barton and Aulenbach are extreme athletes and extreme scientists - scientists who gather their data in treacherous places where few dare to follow. In Journey Into Amazing Caves they travel to caves in Arizona, Greenland and Mexico searching for discoveries that may lead to cures for human disease.
- A story about Sam Johnson reconnecting with his late father. Sam is the fourth generation leader of SC Johnson. In 1935, Sam's father flew from Racine, Wisconsin, to Fortaleza, Brazil in a now nonexistent water plane. Starting in 1998, Sam had the plane rebuilt, and in 2000 recreated the journey. Along the way, Sam shares deeply personal stories about himself and his family.
- The boundary between land and sea is an exciting place, with seabirds, turtles, and marine mammals constantly coming and going.
- The deep sea, which gets darker with increasing depth until no more sunlight penetrates at about a kilometer depth, and ever colder closer to the bottom of the ocean, covers most of the planet and is thus by far the largest habitat on earth, yet has been explored less than space, so most scientific expeditions, at depths requiring modern submarine technology, discover at least one new species, or even whole new branches of submarine life. Like everywhere else, evolution has over millions of years produced several amazing adaptations to even the most extreme conditions, here especially to the lack of sunlight, with its problems for procreation, searching food and fleeing hunters, such as photophore cells which produce specific light types, mimic rare light penetrating from above, etcetera.
- Coral reefs are the rainforests of the sea; fish compete for food, territory and mates within this oasis of life. Incredible time-lapse photography shows the dramatic formation of a coral reef, portraying its inhabitants and its ultimate destruction.
- Life on the edge of a frozen sea is tough. Ice at both poles is constantly moving, and in winter freezes solid with air temperatures 70 °C below freezing. Only in spring, with the retreating ice and light reaching the water, does life begin again.
- The ocean's influence dominates the world's weather systems and supports an enormous range of life. This first episode demonstrates the sheer scale, power and complexity of the "Blue Planet".
- Endless blue stretches in every direction. The sea bed is a staggering eight kilometers deeper down and the nearest island is 500 kilometers away. There is nothing save the burning sun above and the blackened abyss below. How, then, does life exist?
- Shafts of sunlight are the vital source of energy used by the countless billions of plankton that grow every spring and summer in the world's temperate sea, the richest of all habitats.
- Tidal marshes are one of the most productive parts of the world. Numerous plants support numerous animals, yet life is not easy: predators are attracted to these enormous quantities of food, forcing animals to seek constant protection from attack.
