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. It is as if he never existed. But Vidya will not give up her search. Somewhere in Kolkata she will discover the dangerous truth.
