Siddharth Soundaarajan (Naga) is an upcoming violinist in Chennai, who stumbles upon an accident where a teenage girl (Prayaga Martin) is lying in a pool of blood. He rushes her to the hospital with the help of an auto driver and a couple. However, he is too late and the girl passes away holding his hand. Traumatized by the whole episode, Siddharth comes home with one of her slippers. He then drives around the city aimlessly with his red car while helping homeless people, unable to come out of the depression due to the girl's death.
