Gera tackles class in India in love story "Sir" As a child, Rohena Gera never understood why her family's live-in nanny, the "woman she loved like a second mother" was kept at arm's length by her Indian family. In a country where millions of servants sleep on the floor of the homes they work in, the idea that a "master" might fall for the meek low-caste woman who is there to cook and scrub for him seemed "inconceivable", she said. But that is the premise of Gera's new film, "Sir", an upstairs-downstairs love story of a kind she says has never been seen in an Indian movie. IMAGES AND SOUNDBITES with Rohena Gera
