The world of the armoured creatures is equally fascinating and bizarre. Galapagos giant tortoises solve the problem of making love in a suit of armour; a heated sea turtle orgy leaves females in mortal danger and we witness the explosive arrival of a baby pig-nosed turtle. Giant salt-water crocodiles crowd a flooded river-run to fish for mullet and a caiman leads her brood in a touching trek to a communal crèche.

Each year more than one million wildebeest and zebra invade the Serengeti grasslands, making it a paradise for the predators that live there. But what happens when the herds move off again? We follow the moving story of one lion family's struggle to survive until the return of the great migration. Nature's Great Events tells the story of the epic trek of herds that follow the rains to fresh pastures, and the tale of the predators they leave behind.
The crew captures the desperate plight of a single pride of lions, revealing a different side to the Serengeti. Rather than being a predators' paradise, it is a land in constant change, with wildebeest following the rains and leaving the lions to tough it out. The Ntudu pride has seven cubs, and is already suffering as the wildebeest leave to find fresh pastures. The four pride females struggle to find enough food for their hungry offspring. As weeks turn to months, the pride members become more emaciated and frailer, and the number of cubs dwindles to just two. As the herds begin to return, the plains reveal one final secret. For the first time since 1967 the Serengeti's only active volcano, Ol Doinyo Lengai, begins to billow ash and smoke. Filmed from the air, the team captures the exciting action. Fertilised by the volcanic ash over millions of years, these short grass plains are among the most productive grasslands in the world. After months of hardship, the pride's tragic story, through sickness, drought and fire, is over as the herds return, providing plentiful food.

Every summer in the seas off Alaska humpback whales, sea lions and killer whales depend on an explosion of plant life, the plankton bloom. It transforms these seas into the richest on Earth. But will these animals survive to enjoy the great feast? The summer sun sparks the growth of phytoplankton, microscopic floating plants which can bloom in such vast numbers that they eclipse even the Amazon rainforest in sheer abundance of plant life. Remarkably, it is these minute plants that are the basis of all life here. But both whales and sea lions have obstacles to overcome before they can enjoy the feast. Humpback whales migrate 3,000 miles from Hawaii, and during their 3 month voyage lose a third of their body weight. In a heart-rending scene a mother sea lion loses her pup in a violent summer storm, while another dramatic sequence shows a group of killer whales working together to kill a huge male sea lion.
In late summer the plankton bloom is at its height. Vast shoals of herring gather to feed on it, diving birds round the fish up into a bait ball and then a humpback whale roars in to scoop up the entire ball of herring in one huge mouthful. When a dozen whales work together they employ the ultimate method of co-operative fishing - bubble net feeding. One whale blows a ring of bubbles to engulf the fish and then they charge in as one. Filmed from the surface, underwater and, for the first time, from the air, we reveal how these giant hunters can catch a tonne of fish every day.

Nancy Silverton describes her life path involving both Los Angeles and Italy, her family and her obsession with bread. She was born in Sherman Oaks, CA in a family where going out to eat was considered a special treat. But when she entered college and found herself 'very attracted by a handsome man' who worked in a kitchen, she landed herself a job and a new passion.
These details, which all lead up to her stint at Wolfgang Puck’s celebrated LA restaurant Spago in 1982, are intercut with present-day scenes of Silverton working at Osteria Mozza.

Ludo Lefebvre apprenticed under – and learned from – some of France’s most esteemed chefs, but it took a move to Los Angeles, starting a family and a rough restaurant review for him to figure out what he really wanted to do with his culinary future.
This episode examines the ties between artists and their education, and how childlike wonder can, in fact, translate into a career. The question Ludo poses is whether an artist follows instinct, training or intuition… or perhaps all three.

Chef Ludo Lefebvre began his US career cooking at Los Angeles restaurant Bastide, but after it closed for renovations he opted not to return and instead chose to do things his way. Borrowing a friend’s bakery space, which was closed in the evenings, Ludo created a unique dining experience in the form of small, reservations-only, “chef’s choice” dinners. These dinners became known as LudoBites, a pop-up deemed by Pulitzer Prize-winning food critic Jonathan Gold as "a transforming moment” for the LA dining scene.
