In the forests of western Nepal, a team of cinematographers and big cat experts undertake an expedition to follow the lives of two tiger mothers and reveal how these solitary cats are raising cubs on an island full of threats. By using a fleet of drones to track tigers from the air, and military-grade thermal cameras to follow them in the dark, the team witnesses tiger behavior that has never been recorded before. When a new male tiger arrives on the island, an experienced tigress must use all her experience to keep her cubs out of harm's way, while a first-time tiger mother struggles to deal with the threat, leaving her three cubs in grave danger.

On the southern edge of the Sahara in Fongoli, Senegal, lives a group of remarkable chimpanzees that could hold clues to how we became human. The Fongoli chimps live at the very limits where chimps can survive, having adapted to the extreme heat and dryness of the savanna woodlands. For years, these chimps were elusive ghosts, rarely seen. NATURE traces the remarkable 25-year story of how American anthropologist Jill Pruetz and local chimp expert Dondo Johnny Kante got so close to the Fongoli chimps to uncover unique behavior, including hunting with spears, sheltering in caves, digging wells, and reading fire. Seeing into their secret lives and recording extraordinary new behaviors shine a light on our own evolutionary past and fundamentally change how we think about ourselves.

With bulbous eyes, two long sharp tusks, a long mustache and one ton of blubber, the walrus is far from majestic. But for Kirk Johnson, scientist and Sant Director of the Smithsonian National Museum of Natural History, the walrus has been a creature close to his heart for 30 years. Johnson will follow his passion and trek across the Arctic to uncover the hidden lives of these lumbering giants, their cultural significance to the native peoples of the North, and the threats they face as climate change shrinks the sea ice. Johnson will explore the walrus' evolutionary past and reveal the creature's ability to adapt, survive and thrive through the ages. With global climate change, perhaps this colossal creature will be forced to adapt once more.
