Vinod (Mohanlal) becomes mentally ill after his girlfriend Anitha (Lizy) dies because of an electric short circuiting accident during a rock concert. Vinod is admitted into mental hospital managed by Dr. Ravindran (M. G. Soman).
With the help of Dr. Savithri (Karthika), who is Dr. Ravindran’s daughter, and Dr. Unnikrishnan (Nedumudi Venu), Vinod slowly regains his memory and mental equilibrium. Savithri and Vinod fall in love. Dr. Ravindran has already arranged Savithri’s marriage with Hari (Mukesh), so he opposes the lovers.
When he finds that Savithri and Vinod are adamant, Dr. Ravindran lobotomises Vinod and puts him in a state of coma. Dr. Unnikrishnan feels that death would be preferable over a vegetative life and kills Vinod. He confronts Dr. Ravindran and confesses to the euthanasia. Savithri overhears the conversation, and loses her mental equilibrium. She is admitted into the same institution as a patient.
