This movie is based on the people and emotions related to the land of joy, Kolkata. India’s second-biggest city is a daily festival of human existence, simultaneously noble and squalid, cultured and desperate, decidedly futuristic while splendid in decay. By its old spelling, Calcutta readily conjures images of human suffering to most Westerners – although that's not a complete picture of this 350-year-old metropolis. Locally, Kolkata is regarded as India’s intellectual, artistic and cultural capital. Although poverty is certainly apparent, the self-made middle class drives the city's core machinery, a nascent hipster culture thrives among its millennial residents and its dapper Bengali gentry frequent grand, old colonial-era clubs. As the former capital of British India, Kolkata retains a feast of colonial-era architecture contrasting starkly with urban slums and dynamic new-town suburbs with their air-conditioned shopping malls. Kolkata is the ideal place to experience the mild yet complex tang of Bengali cuisine. Friendlier than India’s other metropolises, this is a city you ‘feel’ more than simply visit.

Back in the eighteenth century, Kolkata was British India’s most important trading post and the showpiece of their colonial power. Today the city is regarded as the artistic and cultural capital of India.
