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.

Si and Dave 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.
