Soon the day came when the young brothers and sisters stood at the same window of life from where they have to select the road of sacrifice and the road of selfishness, the story of Do Raaste is the drama of those brothers and sisters who take the different roads. It is the drama of their love and hates. It is the drama of a rich girl love for a poor boy.
