The last of the series in which Simon Parkes looks behind the images of poverty and squalor most often associated with Calcutta.

Parkes examines what the future holds in store for a city that has seen far better days. He meets Manish Chakraborti, a local architect who is promoting the concept of restoration and heritage in a city which is bursting at the seams and where over 60 per cent of the population live in slums.
