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.

Americans define themselves in the superlative: we are the biggest, strongest, fastest country in the world. They reward above all else: winning – at sport, at business and at war.

And epic film by Adam Curtis that explains why the big stories that politicians tell us have become so simplified that we can’t really see the world any longer. The narrative goes all over the world, America, Britain, Russia and Saudi Arabia, but the country at the heart of it is Afghanistan. Because Afghanistan is the place that has confronted our politicians with the terrible truth, that they cannot understand what is going on any longer". The coumentary reveals the forces that over the past thirty years rose up and undermined the confidence of politics to understand the world. And it shows the strange, dark role that Saudi Arabia has played in this. But Bitter Lake is also experimental. Curtis has taken the unedited rushes of everything that the BBC has ever shot in Afghanistan - and used them in new and radical ways. He has tried to build a different and more emotional way of depicting what really happened in Afghanistan. A counterpoint to the thin, narrow and increasingly destructive stories told by those in power today.
