Jyothi is introduced to us as a primary school teacher who does not have a sense of smell. She is inferior about her disorder and tries her best to help out the needy as her carelessness in childhood leads to her mother's death, which in turn changed her as a person. She also gets introduced to Jagannathan, who falls hook, line, and sinker for Jyothi at first sight. Jagan proposes his love for Jyothi on one side, while some murders weirdly take place in the city on the other. It is later revealed that Jagan is a Food Safety Inspector, who is a crusader against food adulteration happening in various food outlets in different parts of Tamil Nadu, ordering the closure of the outlets when he detects adulteration. He is also shown to have a strong sense of smell. His crusade against food adulteration induces many enemies in his path, including his own higher officials in the Food Safety Department, who attack him. Jagan fights them but gets mortally weakened, after which he decides to give up his life by falling off a train onto a banyan tree. Jagan's soul then inhabits Jyothi's body and she inadvertently murders the people who were responsible for food adulteration and Jagan's death.
