Decorated Vietnam hero Frank Vega returns home only to get shunned by society leaving him without a job or his high school sweetheart. It's not until forty years later when an incident on a commuter bus (where he protects an elderly black man from a pair of skin heads) makes him a local hero where he's suddenly celebrated once again. But his good fortune suddenly turns for the worse when his best friend Klondike is murdered and the police aren't doing anything about it.
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.
