Ritesh, a popular film star (Jackie Shroff) and his wife Pooja (Dimple Kapadia) live a wealthy lifestyle with their seven-year-old child Romi. However, after a series of unexpected box office failures and huge losses, he is hounded by creditors and consequently, the couple sell all their personal property and belongings. Frustrated and embittered by his career dive, Ritesh becomes an alcoholic. Pooja, who takes it upon herself to look after the family, works several jobs. This leads to continuous differences between the two, and Romi, their child, becomes a silent spectator to their constant fights and disputes at home.

One day, in a hotel where Pooja works as a chambermaid, she is molested by a hoodlum. A stranger called Alok (Anupam Kher) saves Pooja from him and offers her a job in his firm, much to the annoyance of Ritesh, who would prefer that she stay at home. Ritesh feels it is the last straw for him. He asks Pooja to choose between her job and her family and house. She leaves. Ritesh wins Romi's custody, but soon discovers that Romi is going to die from brain cancer.

To sustain their child's happiness and to overlook his condition, Ritesh and Pooja agree to reunite and spend time together, fulfilling all his wishes before he passes away. Thrown together under the shadow of their child's upcoming death, Ritesh and Pooja, in experiencing the traumatic ordeal, rediscover themselves and each other.

His performance here is heart rending and it rates alongside Gardish and Parinda as one of his best performances... Dimple Kapadia has always been an actress of substance and she pulls of this role with élan and ease... It is Jackie and Dimple which make this film such a classic."
