Marine mammals are the focus of this segment on coastal sea life. Humpback whales mostly swim along the coasts, whether in the Northern or Southern Hemisphere. Seals are semi-aquatic and try to stay as close to the coast as possible, though they'll search for prey in depths of up to forty meters.

California sea lion communication, mating habits, and past and present threats to their survival are discussed. This segment additionally features amazing aerial photography of their rocky coastal habitats.

The video starts with information about coastal geology and the evolution of birds. It includes amazing footage of white storks, wildebeest, as well as zebras in East Africa's Serengeti region.

The focus of this segment is on animals of the African savanna. We get to see giraffes and elephants, the largest of the land creatures, as well as cheetahs, the fastest.

Rhinoceroses, or rhinos for short, are the largest land animals after elephants. Five species remain (two in Africa and three in Asia) and all are endangered as a consequence of the illicit trade of their horns. The importance of rivers is another focus of this segment.

The series draws to a close with footage of apes, the most direct ancestors of humans. The narrator nicely sums up the meaning of evolution and man's place in nature.

Claire’s injury is serious and this time she can’t just push through it. Coach Julian sends her to the best rehab clinic available, which to Claire’s annoyance is in a remote location in the mountains! Just getting there through the snow proves to be a challenge.

High in the snowy mountains, the West Ridge rehabilitation clinic is a lot more relaxed than Claire would like it to be, especially with the pressure of Nationals coming up. When it looks like the rehabilitation plan will simply take too long, she calls up her coach. In the meantime Luke is back, this time delivering logs for the fire.

Claire takes the shuttle into town and immediately bumps into Luke again. He can advise her where to get her skates sharpened, and as it turns out, also seems to know quite a lot about skating! In search of a place to practice, Claire makes a naïve decision when she finds a frozen lake.
