The Marathi film Sairat has been running to packed theatres across the country since its release earlier this year. A love story between an upper caste girl and a Dalit boy, it has all the familiar trappings from the wildly popular song and dance sequences to picturesque locales, but ends with a brutal reminder of the caste realities of 21st century India. This week India Matters in the episode, 'The Consensual Killings', explores the reasons for the success of Sairat and why caste divides still run deep in our society.
