The two people in focus are Srinivasan (R. Parthiepan) and his good friend Dharan Viswanath (Ranjith). Seenu is a loving husband of Shanti (Divya Unni), and Dharan is Shanti's ex-lover. Life is going great for Shanti and Seenu until Seenu loses his eyesight in an accident.

One day, Srinivasan and Dharan find that Shanti has died by hanging herself in their house. The police close the case as a suicide. Evidence surfaced which point to Dharan's guilt, but he resolutely maintains that he is innocent, while Srinivasan too believes him. It keeps the suspense alive successfully: with respect to Dharan's innocence and the reason behind the happenings. Srinivasan seems convinced that his wife has been murdered. One day, Dharan discovers that Seenu is not blind after all.

Who murdered Shanthi? Or was it suicide? Why did Seenu pretend to be blind? The answers to these questions form the rest of the story.
