The story exposes the ego clashes and complexities of a period through the eyes of its lead character Thanu Pillai (
Lal), who witnesses the tale of three women, his mother, wife, and son's wife. Fifty-five-year-old Meenakshi Pillai who is married to seventy-one-year-old Thanu Pillai files for divorce from her husband and demands the return of the properties he had her transfer in his name during their marriage. Advocate Balamany, the defense lawyer, tries to convince Meenakshi and her son Sarath Chandran to withdraw the case on various occasions. Sarath tells her that his father was abusive and harsh towards him and his mother. He also tells her about Kali Pillai, Thanu Pillai's mother, who was lord of a feudal family which followed matrilineal succession and had considerable power in the local politics and among people. Thanu Pillai was also very harsh towards his mother and even hated the matrilineal system. Hence, he married Meenakshi from a
Nair family which followed the patrilineal system. Even though Meenakshi was from a poorer family, Kali Pillai loved her and even advised her many times to take a stronger stand against her husband instead of submitting to patriarchy. However, Meenakshi remained submissive to her husband all through their marriage. Sarath and Balamany slowly develop a relationship. As the case progresses, more and more things from the past are revealed from the perspectives of various people in Thanu Pillai's life. Meenakshi lived through this cycle of abuse because she knew that her husband deeply loved his son. It is also revealed that the only reason Sarath is alive and in good health is because of his father. This makes Sarath change his view towards Thanu Pillai. It's also revealed that Sivan Pillai, Thanu Pillai's father, was a wrestler who died penniless because Kali Pillai divorced him to live with a younger, educated man. This scarred a young Thanu Pillai deeply, causing him to be harsher towards his mother and become abusive towards his wife even though he loved both of them. Kali Pillai before her death asks Meenakshi to call Thanu Pillai but he refuses to see her, which causes Kali to storm out of the house and die in the streets. Thinking about his mother's death caused Thanu Pillai to suffer a heart attack later a few months ago. After recovering, he asks his wife what caused his mother to leave the home, accuses his wife of hurting his mother, and even calls her a slave. This affects Meenakshi, driving her to file for divorce. She tells Balamany that she wants to live and die independently like her mother-in-law. Thanu Pillai suffers another heart attack but he is cared for by Meenakshi and recovers. The next day in court, Thanu Pillai, Sarath, and Balamany are hopeful that Meenakshi Amma will withdraw her divorce petition as she took care of Thanu Pillai when he was ill. But she insists in court that she wants a divorce. A pained Thanu Pillai agrees to all demands of Meenakshi in court. On his way back home with Sarath, he reveals to his son that he was abusive towards Meenakshi and Kali Pillai because he was afraid of them due to his father's fate. He tells his son that Balamany is a strong woman and approves of their relationship, but also advises him to never be scared of her, and that fearing his wife made him try to put her under his feet always, which was a mistake. When they reach home, Thanu Pillai and Sarath are surprised to find Meenakshi at home. She has prepared a sweet dish and hands it to Thanu and says she will come to look after him when he is not well, but not as a wife. Meenakshi, a free woman now, spends the rest of her life in the house Kali Pillai had gifted her, with pride and self-respect like Kali Pillai did. ==Cast==
