Uday, is a rich kid who becomes the chairman of a company following his father's death He believes in the adage of life is short and carpe diem. At a New Year's Party in 2007, he spies on a girl called Sandhya in a salwar kameez, writing a diary at the pub.

Through a series of searches with his friend Fatso, he ends up discovering that Sandhya lives alone at a beachside house and runs a nursery. She is very traditional with her own ideals. He enters her house on the pretence of being a paying guest to make her fall in love with him. After a series of attempts to woo Sandhya, Uday eventually succeeds and presents her with 12 gifts on her birthday, the last being Uday himself.

In a subplot, an insurance salesman named Abhishek ends up trying to show his younger and reclusive colleague "how to be a man" in many lessons that often result in the latter's physical pain. Eventually, the duo collides with the story's main plot when they attempt to sell Sandhya life insurance (which she later agrees to buy). When asked who the beneficiary of the policy should be, she writes Uday's name. When Uday hears this, he thinks that he has won Sandhya. However, it is revealed to Uday (through the insurance policy which has now been rejected) that Sandhya is suffering from breast cancer (lobular carcinoma) and has limited time left.

In the ensuing part of the film, Uday takes Sandhya on a cruise to Calcutta to spread her parents' ashes in the Ganges River. They run into several comic characters on their journey, including a kidnapped Abishek who tries unsuccessfully to tell Sandhya that her policy was rejected because of her illness; his attempts are thwarted by Uday. These circumstances help Uday teach Sandya how to live life, and back from the trip, Sandhya and Uday throw a Christmas party at Sandhya's beach house. However, Sandhya collapses in the aftermath of the party and discovers the truth about her health.

Sandhya eventually falls in love with Uday and says that she wants to spend the last days of her life with him. The ending scene has Uday and Sandhya sitting on a bench in the rain with a "Welcome 2008" sign in the background on New Year's Eve. The scene then fades to Uday sitting alone with a "Welcome 2009" sign in the background one year later waiting for the rain. This infers that Sandhya has died, but Uday still keeps her memories close to her heart. The film ends with Uday leaving after the rain.
