Choices: to choose between right or wrong is simple, but what defines one's life is the decision between the greater of two goods or the lesser of two evils. This is the advice that Zooni Ali Beg (Kajol) receives from her father just as she is about to venture out into the world on her own for the very first time. Little does she know that these very words will shape her life. Zooni, a blind Kashmiri girl, meets Rehan Qadri (Aamir Khan), a local Delhi tour guide and an incorrigible flirt. Her friends warn her against this good-for-nothing roadside Romeo, but she chooses to ignore them. It is now her time to discover life and love. Is this really the right choice? Rehan is fascinated by Zooni and wants her to see life as it should be seen, in its many colours. He promises her that the time spent with him will be the most precious in all her life. Zooni sees Delhi, life, and love like she never has before, because of Rehan. What Zooni doesn't know is that Rehan has another side to his life--something that can not only change her life, but can also destroy it. Written by Official Source
