And at its very tip, is Babylon, Vishnu Rustomji Mistry's famous garden on top of the tallest building in Mumbai the centre of its wealth and power. It's the day the flamboyant billionaire will make his big announcement. Yet, it'll be one of the few days in the year when his won't be the biggest story.

When model-turned-newscaster Tara and rookie journalist Sudhir Navkar stumble upon clues about this possible vigilante, they are led on a breadcrumb trail from the eerie slums of gangland Mumbai to the high-rise towers of SoBo. As the two of them try desperately to solve the mystery, they begin to uncover a frightening conspiracy that threatens to cast a shadow on the entire nation and on their lives. In a choice between love, life and their karm, will they have the courage to pursue the truth?
