Vidya Bagchi (Vidya Balan) arrives in Kolkata from London to find her missing husband Arnab Bagchi. Seven months pregnant and alone in a festive city, she begins a relentless search for her husband. With nothing to rely on except fragments from her memories about him, all clues seem to reach a dead end when everyone tries to convince Vidya that her husband does not exist. She slowly realises that nothing is what it seems. In a city soaked in lies, Vidya is determined to unravel the truth about her husband – for herself and her unborn child – even at the cost of her own life.
