In Bhutan, Palin finds himself back in the land of yaks for a last look at the high Himalaya. Trekking to Chomolhari base camp he meets a nomad with a penchant for yak songs before heading down to Paro to witness the Buddhist festival or Tsechu. In a bar in Thimphu, he discusses reincarnation and the pursuit of happiness with Benji and Khendum, two of the king's cousins, and en route to Bangladesh is taken by Benji to see the rare black-neck cranes. On his journey south through Bangladesh, Michael visits the ship-breaking beaches of Chittagong and grid-locked Dhaka. He meets a man who made a fortune in Birmingham in the poultry business, and a woman who lends money only to women. On a 1920s paddle steamer he is serenaded with the words of Bengal's Shakespeare, and he completes his epic Himalayan journey aboard a fishing boat that carries him out into the Bay of Bengal and a westering sun.

Prepare yourself for an unparalleled sensory experience. Samsara reunites director Ron Fricke and producer Mark Magidson, whose award-winning films Baraka and Chronos were acclaimed for combining visual and musical artistry. Samsara explores the wonders of our world from the mundane to the miraculous, looking into the unfathomable reaches of humanity's spirituality and the human experience. Neither a traditional documentary nor a travelogue, Samsara takes the form of a nonverbal, guided meditation.

The second episode is about how plants gain their sustenance. Sunlight is one of the essential requirements if a seed is to germinate, and Attenborough highlights the cheese plant as an example whose young shoots head for the nearest tree trunk and then climb to the top of the forest canopy, developing its leaves en route. Using sunshine, air, water and a few minerals, the leaves are, in effect, the "factories" that produce food. However, some, such as the begonia, can thrive without much light. To gain moisture, plants typically use their roots to probe underground. Trees pump water up pipes that run inside their trunks, and Attenborough observes that a sycamore can do this at the rate of 450 litres an hour — in total silence. Too much rainfall can clog up a leaf's pores, and many have specially designed 'gutters' to cope with it. However, their biggest threat is from animals, and some require extreme methods of defence, such as spines, camouflage, or poison. Some can move quickly to deter predators: the mimosa can fold its leaves instantly when touched, and the Venus flytrap eats insects by closing its leaves around its prey when triggered. Another carnivorous plant is the trumpet pitcher that snares insects when they fall into its tubular leaves. Attenborough visits Borneo to see the largest pitcher of them all, Nepenthes rajah, whose traps contain up to two litres of water and have been known to kill small rodents.

Served crispy and sizzling in grease. When it comes to preparations, few could be as delightful and decadent as a good, old-fashioned deep fry. We dip the Mind of a Chef basket in hot oil on this episode, serving up everything from oyster poboys to pig’s head, from alligator filets to sardine spines.

They have the raw talent, but can they handle the pressure? Now Yuki Tsunoda and Esteban Ocon must sink or swim in the rough waters of Formula 1. Yuki Tsunoda had to move from Tokyo to Milton Keynes and F1 cars are proving a bit more difficult to wield than the F2 machine in which he won races. Esteban Ocon is part of the all-French attack (from Enstone) in the shape of Alpine, soaking up the pressure to win the Hungarian GP.

Under the management of new team principal Otmar Szafnauer, Alpine F1 Team goes into 2022 retaining their drivers Fernando Alonso, a veteran of Team Enstone and two-time Champion, and Esteban Ocon, the driver who took Alpine to their first victory since 2014, with a new reserve driver in Australian driver and 2021 Formula Two champion Oscar Piastri. Alpine scores consistent points scores in Miami, Baku, and Austria.
By the French round - the home race of Alpine - McLaren and Alpine are tied for sixth in the Constructors' Championship. Early into the race, Alonso edges past Lando Norris for fourth, with Ocon behind him. However, Ocon inadvertantly takes Yuki Tsunoda out of the race, giving him a five-second penalty. Pitting soon after drops him down out of the points, with Alonso now sixth and a second behind Norris. Alonso holds the McLarens up to buy enough time for Ocon to pass them. Alonso finishes sixth and Ocon eighth in their home race.
Before Hungary, it is revealed that four-time Champion Sebastian Vettel will retire from Formula One, sending the paddock and media into a frenzy with the prospect of a ‘silly season’ on the horizon for Aston Martin; Szafnauer is adamant that Alonso is staying with Alpine for 2023. Hungary is the make-or-break round for Alpine - both drivers need to score higher points than McLaren to achieve fourth in the Constructors' Championship. Ricciardo and Lance Stroll both overtake the Alpines, but Ricciardo punts Stroll off the track, giving him a five-second penalty. Alonso and Ocon barely hold on to the points, and Ricciardo finishes fifteenth after his penalty, allowing Alpine to secure fourth place. The team and their title sponsors BWT celebrate at a sponsor dinner. The next day, Alonso reveals he had received a call from Aston Martin team owner Lawrence Stroll to replace the outgoing Vettel, moving him out of Team Enstone. Left with no other option, Alpine announce Piastri for the 2023 season, and McLaren are looking to replace Ricciardo with Piastri, who they have had eyes on. To make matters worse for Alpine, Piastri announces on Twitter that he will not be driving for the team, considering he had not signed such a contract with them.
