Like so many Bollywood love stories in the past, Maine Dil Tujhko Diya is about boy-meets-girl. In this case, Ajay (Sohail), an orphan meets Ayesha (Sameera), and they fall head over heels in love. However, as much as they want to spend the rest of their lives together, there is a major problem in their way.

Ayesha's father Verma (played by Kabir Bedi) is not pleased with his daughter's choice of partner and vows to separate the two lovebirds. He even goes to the extent of using the underworld to help him in his quest. This is where popular actor Sanjay Dutt makes his special appearance as Bhaijaan - who is entrusted with killing Ajay.

However Bhaijaan, a devoted Muslim, is unable to perform his task as it's the month of Ramadan and feels it would be against his religion to murder someone. So he decides to wait till the Chand Raat (the end of Ramadan) and during this time tries to make Ajay see sense. So what happens after that? Does true love overcome the injustices thrown in its path and win the day…?
