Anjooran (N. N. Pillai), and his four sons Balaraman (Thilakan), Swaminathan (Innocent), Premachandran (Bheeman Raghu) and Ramabhadran (Mukesh) are in severe enmity with the Anappara family. Anjooran's bitter hatred toward Anappara Achamma (Philomina) stems from events in the past, when the men of Anappara abducted Balaraman's fiancÃƒÂ©e and forced her to marry the eldest son of Achamma. The resulting series of events saw Anjooran's wife being killed, and him being sent to jail for avenging her by murdering Achamma's husband. Consequently, he develops a hatred toward all women, and their entry into his home is prohibited from then on.Anjooran's youngest son Ramabhadran is a law student. At college, he and his friend Mayin Kutty (Jagadish) try all means to humiliate their classmate Malu (Kanaka), who is the granddaughter of Achamma. Malu gets engaged to a state minister, but the minister withdraws from the relation as Anjooran intervenes and threatens him of political consequences. Incensed, Achamma hatches a plan to divide Anjooran's family by having Malu seduce Ramabhadran and making him turn against his father. When Malu expresses her feelings to Ramabhadran, as per the advice of her grandmother, Mayin Kutty ideates that Ramabhadran could divide the Anappara family by seducing Malu and turning her against them. On his advice, Ramabhadran too acts as if he is in love with her. The facade soon falls and they really fall in love with each other. While wondering about ways to get his family to support this relationship, he gets to know that Swaminathan is leading a secret double life as Ramanathan, with a wife Kochammini (K. P. A. C. Lalitha) and two kids. When confronted with this information, Swaminathan promises to help unite him and Malu.Through a turn of events, Anjooran comes to know of Ramabhadran's love affair and Swaminathan's deceptiveness. Consequently, they're both ostracised from the family. Over at Anappara, Achamma is shocked to know that Malu's love is not a mere act. She and her sons decide to get her married to the family's advocate's son (Ravi Vallathol). However, she still tries to bring her plans to fruition by sending out signals that the house is divided over the issue. To this end, she sends her sons to beg for Anjooran's help in preventing Ramabhadran from marrying Malu (a request that Anjooran approves), and approaches Ramabhadran herself assuring him of all help in doing so.However, Achamma does not know that her youngest son Veerabhadran (Siddique) is sympathetic to the lovers' cause and has revealed her plan to Ramabhadran. With his help, Ramabhadran sneaks in to the marriage hall and almost marries Malu. Enraged, Achamma curses Anjooran for not being vigilant enough, exposing her duplicity. Ramabhadran then admits that he sneaked in not to marry Malu, but to foil Achamma's plan and save his father's honour. A regretful Anjooran allows the wedding of Ramabhadran and Malu to take place and welcomes both him, Swaminathan and their families back into the fold, thereby paving the way for the entry of women into his house once again.
