Amar Kaul (Vinay Pathak) is a 37-year-old accounts manager at Suraj Pharmaceuticals in Mumbai. He is single and lives with his mother (Sarita Joshi). He lives a nondescript life with people oblivious to his existence. One day his doctor tells him that he will die within three months due to stomach cancer. Realising that his time is limited, Amar makes a list of ten things he wants to do in his life and sets out to do them. They are:
- Buy a red car.
- Tour abroad.
- Play guitar.
- Confess his unrequited love for his childhood crush, Neha.
- Stand up to his boss.
- Visit his old friend Rajiv Jhulka.
- Experience romance.
- Reveal his condition to his mother.
- Have his photo published in the newspaper.
- Mend his relationship with his younger brother.
He finds the true joys of life in a few months, which were hidden all his life. After three months, at the time of his death, he leaves something for all his loved ones, leaving them happy and thankful to him.
