Unni is a
share broker in
Coimbatore and leads a comfortable life with his wife, Latha, and daughter, Lakshmi alias Lechu. Into the cosiness of such a living intrudes a stranger who introduces himself as Jose. Cashing in on Unni's forgetfulness, Jose goads him into believing that he is Unni's 7th-grade classmate. However, a sense of insecurity pervades, with the unwelcome guest – alcoholic and somewhat eccentric – pitching for an extended stay. Unni's misgivings about the 'mystery man' and his ulterior motives prove true, when his confidant and classmate, Dr. Alex Varghese, on consultation, reaffirms his doubts that they had no schoolmate in the name of Jose. Soon, they discover to their horror that Jose is Sivankutty, a man whose arrival they have been dreading for a long time now. It is eventually revealed that Unni and Alex ruined Sivankutty's life by framing him in a
murder which they had accidentally committed in their childhood. The duo realizes that it is payback time and that they are at the receiving end. Sivankutty compels Unni to accompany him back to his village and confess the crime to Sivankutty's wife Jaya and daughter Meenakshi, who have left him after they found out the secret that he has been in jail. Midway, Unni decides to abandon the plan of meeting Sivankutty's family and attempts to come back to
Coimbatore but is threatened to accompany him. Alex joins Unni in meeting Sivankutty's family. Unni and Alex confess their crime to Sivankutty and finally agree to tell the truth about the murder to his family. However, when they reach his house, they find out that his Jaya and Meenakshi have already passed away. Sivankutty reveals that his intention of bringing them to his town was to kill them for revenge, but he changes his mind and lets them go back after they confessed their mistake. ==Cast==
