- Aging cowboy Will Penny gets a line camp job on a large cattle spread and finds his isolated cabin is already occupied by an abandoned woman traveler and her young son.
- Rodents are the most numerous mammals on the planet, comprising an incredibly diverse variety of species. They range from the naked mole rat, which spends its entire life below ground, to the world's largest rodent, the capybara, which grazes in herds across the vast grasslands of South America. In the fourth of his ten-part epic series David Attenborough shares his fascination with these animals, which stop only at his pet hate - rats.

- 2009–4.3 (9)TV EpisodeIn the episode we look at how animals swarming together create a collective intelligence. Huge shape-shifting shoals of herring use swarm intelligence to detect predators. Billions of alkali flies form a rolling wave to evade the gaping mouths of gulls. Millions of free-tailed bats form a living tornado and still manage to keep from colliding with each other.
- Flora has evolved to live in extreme conditions and a wide variety of locations and seen as the eldest 'creatures' on the planet. Their struggle for life, like animals (only usually much slower), is about food (including parasitism and 'flesh-eating'). They strive to find water, to procreate: notably pollination-mostly by animals and semination - gliding or by weather conditions, or more primitive ways such as spores. They have a varied defense (thorns, spines, toxins etc.). Specific is the need for light, the fuel of photosynthesis, leading to a hierarchy of light-related levels, because not growing high enough in time can be lethal.
- The causes of the million year volcanic eruption in the Siberian Traps and the resulting effects that lead to the largest mass extinction in earth's history are recounted.
