Jayakrishnan participates in a prize winning show,
One Man Show hosted by popular movie star
Mukesh. During the course of the show, the host pries into Jayakrishnan's past, and the whole story is unwound in a flashback. Jayakrishnan, his uncle K. R. Menon, and his cousin (Menon's daughter) Radhika, who is also Jayakrishnan's sweetheart, live together. They are lawyers by profession, and their house is nicknamed "Kodathi Veedu" (courthouse). Among the lawyers of Kodathi Veedu, Jayakrishnan and his Junior Ponnappan are the only ones idle. No client ever comes to Jayakrishnan and hence is unable to earn anything, as he had bungled some cases earlier. While K. R Menon and Radhika are successful lawyers, Jayakrishnan is constantly derided for his failure. However, he decides that he'd marry Radhika only after he has fought and won a legal battle. So Jayakrishnan and Ponnappan decide to reopen the case of Hari Narayanan, who has been in a mental asylum for the past few years. Jayakrishnan, with timely help from Doctor Raziya, his friend, proves in court that Hari Narayanan is not insane by having Hari Narayan answer difficult questions posed by the opposition lawyer K.R. Menon. Jayakrishnan successfully proves that Harinarayanan was dubbed a madman by his own brother Raveendran (Janardhanan), who wants to usurp his assets. Jayakrishnan wins the lawsuit. Hari Narayanan is released from the mental asylum, and Jayakrishnan marries Radhika. But the plot takes a sharp turn when Jayakrishnan discovers that Hari Narayanan is, in fact, insane. Jayakrishnan is helpless as he is ashamed to expose Hari Narayanan's insanity. Meanwhile, the insane Hari Narayanan thinks that it is he who has married Radhika. A series of strange incidents occurs, leading everyone to believe it is Jayakrishnan who is insane. Meanwhile, Hari Narayanan begins to seek revenge on his brother. He bombs his brother's factory, which causes a huge financial loss. Since it was Radhika who legally offered bail for Hari Narayanan, she is held responsible for covering the loss. They are unable to pay this amount, and Radhika goes to prison. It is for her release that Jayakrishnan has come to the TV game show. Everything ends well when he wins the game show and frees his sweetheart. == Cast ==
