All human beings are capable of distinguishing the real from the unreal (imaginary). But there are a few who refuse to recognize this distinction.

Anu (Bipasha Basu), a fine arts student, from a happy and affluent family experiences a tragedy. On September 11, 2001 terrorists attacked New York's World Trade Center, killing Anu's elder sister and her brother-in-law. The impact of the tragedy shook her badly and she had a mental setback.

To help her overcome this problem, her parents get her engaged to Arpit Oberoi (Priyanshu Chatterjee) a well known Ad-Filmmaker, who is later commissioned for an international ad Film project and leaves for the U.S. Meanwhile, Anu meets Aman (John Abraham) who is member of an anti-terrorist organization. Enamored by Aman's purpose in life, Anu falls in love with him.

When it is time for marriage with Arpit, she refuses to marry him and cuts her wrists in protest. Anu survives and it is revealed that she suffers from Schizophrenia.

When and how and whether at all Anu overcomes this dreaded disease & how she deals with the two men in her life forms the interesting conflict of the film.
