Avantika [Kareena Kapoor] is a teacher at a university in Delhi. She has come back from New York where she teaches, because her father [Aakash Khurana] has suffered a heart attack. During this period, she meets a Professor called Ehsaan Khan [Saif Ali Khan]. Soon, they begin seeing each other and love blossoms.

A few months later, Avantika receives a call from her university in New York, asking her to come back. Avantika breaks the news to Ehsaan. He, in turn, tells her he doesn't mind coming to the States with her. But first they need to get married.

Soon after the marriage, they leave to start a new life in New York. They buy a house in an Indian neighbourhood and move in. Just as they are setting up home, their conservative Muslim neighbours invite them over for dinner. The next morning, Salma [Nauheed Cyrusi], one of the women Avantika met the night before at the dinner, visits her under the pretext of gifting her sweets.

When Avantika invites her in, Salma tells her that she is in grave danger. Nothing is what it seems. Salma pleads with Avantika to help her. What follows next is a series of incidents that sucks Avantika into a vortex of danger and intrigue. As her life spirals out of control, Avantika realizes that she is a pawn in a huge game.
