Sirf is the story of four couples and their lives in a metropolitan city. They belong to different social and financial strata and every one has got its own problems to deal with. What one couple has, the other doesn't? Each couple looks at the other couple and wishes that if only they had what the other couple does, their life would be a bed of roses, be it on a monetary level or on moral terms.
In due course of time, all four couples come together with a distant vision of that one event which would end all their problems and set them free. Is it reality or just a figment of their vivid imagination?
