A pregnant woman's search for her missing husband takes her from London to Kolkata, but everyone she questions denies having ever met her husband.
Kolkata is abuzz with the preparations for the annual Durga Puja festival, as seven months pregnant Vidya Bagchi steps off the airplane from London. Her first stop is the local police station to file a missing person report. Weeks ago, her husband Arnab arrived in India for a job assignment. The first two weeks, they talked daily on the phone, and then without explanation, his calls stopped. Everywhere Vidya turns, no one can remember Arnab. There is no trace of him at the guest house or his workplace. But Vidya will not give up her search. Somewhere in Kolkata she will discover the dangerous truth.
Vidya Bagchi arrives in Kolkata from London to find her missing husband. Seven months pregnant and alone in a festive city, she begins a relentless search for her husband.

She slowly realizes 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 her own life.
