Pan Pictures' Nidaan tells the story of a vivacious young teenager hailing from an upper middle class Maharashtrian family, who is the apple of her parents' eyes. The family's happiness is shattered when the girl falls ill and the doctors diagnose Aids, which she had contracted during a blood transfusion in her childhood days. The girl's parents are traumatized and consult every possible doctor to find a remedy for the malaise, knowing that death is inevitable for their daughter. Her boyfriend decides to stand by her and even gets married to her, to see her happy in the last few moments. How the family battles with the tragedy that overcomes them forms the crux of the film.
The first few reels of the film are melodramatic and are spent in establishing the relationship between the daughter and her parents and how they love her beyond everything. It is only when she falls seriously ill that the story gathers momentum. The drama becomes intensely emotional, as the father tries hard to cope up with the fact that the disease is terminal.
The emotional moments towards the end of the first half and the beginning of the second half manage to touch the core of the heart. Towards the end, however, the film starts dragging when the emotional bit is stretched a bit too far. Also, the marriage in the last few reels, besides the father's efforts to get Sanjay Dutt to visit his daughter in hospital, sounds a bit too exaggerated.
