Rahul Singh, a compulsive gambler, has never picked the right horse. Then one day when he risks everything he has, the winning horse comes in making him incredibly wealthy.
The same evening while celebrating his new life, he proposes to his girlfriend Nafisa, and suddenly collapses. A diagnosis reveals that he has an incurable cancer that has already reached its final stage. He is told that he has 90 days to live.
Faced with the realization that death is inevitable and filled with anger at the rotten hand fate has dealt him, he runs away from his home and fiancée to a hospice. Reluctantly at first, and then with a renewed enthusiasm as his anger and self pity dissipate, he begins to live a whole lifetime in the last 90 days.
