The Hairy Bikers roar back into action with a madcap tour of South India, starting in Madras, now known as Chennai, a riot of hustle and bustle and colours and flavours and bullock carts, and heat, lots of heat!

The Hairy Ones travel through the Cardamom Hills high up into tea country, where the Raj still lingers, and Si finds an astonishing piece of his family history.

The Hairy Ones are in the world's eighth biggest country, dividing their time between the full-on urban buzz of Buenos Aires, and the beauty of a traditional estancia, or ranch

t's time for Dave Myers & Si King to head south, leaving Buenos Aires behind as they begin their long ride to Patagonia.

Si and Dave hop the Channel and find themselves in the alternative universe of Belgium, birthplace of surrealism and the finest chips in the world.

Things get really surreal in Brussels when Si and Dave meet a statue of Tintin and walk their way into a Magritte painting, and then try to corner a couple of Members of the European Parliament to find out what's happening to Europe's traditional foods.

The Boys begin their adventures in Marrakech, where Si acquires a carpet and Dave acquires a King Cobra on his head. After treating the locals to a Kefta Tagine cooked in the city's historic square, they go back to school to learn how to cook a classic pastilla.

Si and Dave head into the film town of Ouarzazate, or "Hollywood with camels" as they describe it.
