Harshad Mehta is an ordinary Gujarati salesman who lives in a cramped one-room apartment in Mumbai’s Gujarati dominated suburb of Ghatkopar along with his parents, wife Jyoti and brother Ashwin. After doing all sorts of odd jobs, he joins the Bombay Stock Exchange as a “jobber”. Unsatisfied with his growth, he soon starts his own consulting firm. Exploiting loopholes in the market system and bribing various officials, he soon amasses a huge amount of wealth. In a parallel narrative, journalist Sucheta Dalal is investigating Mehta’s business after getting a tip from a bank clerk about Mehta’s involvement in a scam in State Bank of India.
