Jannatville, a rich, gated community lies across the creek from Pariabad, a large slum which lacks even basic facilities such as drainage and water supply. When a dengue epidemic surfaces in both communities, issues of social justice and public health ethics become prominent. Against this backdrop, an international research team seeks permission from a local IRB to carry out a trial in Pariabad and another locality, for a drug, Fixit-W, that can be added to a community's water supply and which potentially, can kill a mosquito that bites someone who has ingested Fixit-W. Issues such as justice, community engagement and voluntary consent in public health research are highlighted in the movie.
