In the glitzy entertainment capital of Mumbai as dusk descends, famous actress Suna Azim (Kangana Ranaut) slashes her wrists in a hotel room, in an attempt to kill herself. When this news reaches film maker Aditya Garewal (Shiny Ahuja), he is devastated. Aditya has been searching for Sana all over the world. Sana who was intensely involved with Aditya, had mysteriously disappeared from his life without any explanation, three years ago, only to surface now in what could be the last moments of her life.
As Aditya waits outside the ICU in a death watch situation, praying to be reunited with her, he is hurled back into the perfumed days and champagne nights of his memory, wherein Sana Azim played the role of both, lover and mentor to a struggling Aditya.
Everything was perfect, except for an enemy which lurked in the shadow, waiting to destroy their love. An enemy which neither of them saw till it was too late?
When Aditya realizes that the only way he can save Sana from total devastation is to take her away from Bollywood and the vested interests that threaten to destroy her completely, he runs away with Sana putting his career on the line. Those moment lived in the sanctuary of their love are like an oasis in the desert.
Until one day, suddenly, she disappears, leaving him with unanswered question. Why did she leave at the very acme of their love, when there seemed to be hope? What pushed her to attempt suicide? Will be finally be able to piece together the puzzle that has been haunting him and almost destroyed him? And most important of all, will be reunited with his love?
