Along with Sameer who loves her dearly, she plans to let her sister win her love..

Kundan Shah has handled the film well. He has a way with narrating sensitive human relationships. The first half till the interval moves at a smooth pace with light movements in between. The story picks up pace in the second half with a climax that is sure to touch a chord among the viewers.

The cast especially the women has given a beautiful performance. Preity who was also the directors leading lady in his last hit 'Kya Kehna' handles her vivacious, likable character with ease. Mahima Chaudhary, as the gentle and feminine elder sister has given a touching performance. The role of the wealthy, powerful widow and mother is safe with veteran Rekha. Although the men has nothing much to do in a women dominated film Arjun Rampal and Jimmy Shergill has done their parts well. Alok Nath as Arjun Rampal's father in a supporting role is good.

The music by Nadeem - Shravan except maybe for 'Mohabbat' and 'Dil laga liya' is just okay. Overall the film is a touching tale, worth watching.
