Mumbai

For the first time in human history more than half of us live in cities. Vibrant, complex, colossal - what drives their success? Mumbai is 'Maximum City'; the most densely populated corner of the globe where the ambitious come to seek their fortune. In one day in this city of dramatic contrasts we meet one of India's richest businessmen; travel to school with the children of a Mumbai slum; and dress up with one of Bollywood's top costume designers.
