Shiva, an engineering graduate with an attitude, is on the look out for a job. An ebullient and carefree young man, he isn't seriously concerned with seeking employment, while his friends try their best to find him suitable work. In the meanwhile, Shiva spots Charu in a bus stop and it is love at first sight.
Overwhelmed by the intensity of his emotions, he becomes completely distracted by his need to find her identity, and in fact, even misses an interview in her pursuit. Destiny seems to have something good waiting for him and he gets to spend the most beautiful phase of his life, giving her a ride in the car while waiting to pick the owner of the car at the railway station.
Life takes an exciting turn from this point for Shiva, who accepts to drop her in Mumbai and thus begins Paiyaa's journey of romance, action and emotions on a highway with numerous twists and turns, and danger lurking behind a few roadblocks as well.
