Poovalli Induchoodan, the only son of the idealistic High Court Judge Maranchery Karunakara Menon, is wrongfully convicted and sentenced to six years in prison for the murder of a classmate. He later learns that the conspiracy was orchestrated by Home Minister Manappally Madhavan Nambiar and his associate DYSP Sankaranarayanan, who sought revenge against Menon for previously sentencing Nambiar in a corruption case. As a result of his conviction, Induchoodan loses his place in the civil service, which is subsequently secured by Nambiar's younger son, Sudheeran. It is later revealed that the actual murderer was Ramakrishnan, the son of Nambiar's loyal supporter Mooppil Nair.
After serving his sentence, Induchoodan is released from prison following Madhavan Nambiar's death. He returns to Kerala with his parents and soon becomes embroiled in a renewed conflict with Nambiar's elder son, Manappally Pavithran. During this period, a young woman named Indulekha claims to be Menon's illegitimate daughter. Initially dismissed and humiliated by the family, she is later revealed to be telling the truth. Upon learning this from his maternal uncle Chandrabhanu, Induchoodan accepts her as his sister and takes responsibility for her protection.
Induchoodan arranges Indulekha's marriage to his friend Jayakrishnan and persuades Menon to acknowledge her as his daughter. Menon eventually regrets his past actions and privately reconciles with her. However, the following day, Indulekha is found murdered, and Menon is arrested for the crime. The murder is revealed to be part of a plot devised by Pavithran, who kills Indulekha and coerces Menon's longtime servant Raman Nair into giving false testimony against him.
In court, Supreme Court lawyer Nandagopal Marar, a close friend of Induchoodan, successfully exposes the conspiracy and proves Menon's innocence, leading to his acquittal. After his release, Menon expresses remorse for his past mistakes, including his failure to trust Induchoodan's innocence. Shortly thereafter, he suffers a stroke and dies.
At Menon's funeral, Pavithran arrives to mock Induchoodan and resume the funeral rites of his own father that had previously been interrupted. Induchoodan confronts him and exacts revenge for the deaths of Indulekha and Menon by severely injuring him. The film concludes with Induchoodan leaving behind his turbulent past and accepting Anuradha, the forthright daughter of Mooppil Nair, as his life partner.
