There is a proverb which says that whatever is written in one's destiny in some way or the other actually happens. But if we fight against it, and make the incident happen in a different way- then what? The film revolves around a woman named Rashi and the role destiny plays in her life. She is engaged to novelist Vikram Sehgal, who has a weakness for women.
There are two parts in the film both did differentiated by the change of an event in a second. But that one second leads to two very different outcomes. It takes only one second in life to change the course of events, and maybe even our destiny.
