Ushamma Bindu Panicker is the wife of the late Mohan of Kalluvelil Tharavad, a Nair family in Kumbazha. She has three children: Manu Mohan Sharafudheen (the eldest), Meera Mohan Rajisha Vijayan (the final-year MCom student who also runs a home tuition centre), and Malu Meenakshi Warrier (a second-year engineering student at Mount Zion College). When Mohan dies, Manu steps into a position at the family’s community service society, and he is quickly drawn into a complex web of relationships. Manu Mohan Sharafudheen is in love with Shalabha Arsha Baiju, the daughter of Karayogam president Indrasena Kurup Vijayaraghavan. Meera, meanwhile, keeps a home tuition centre and pursues her studies.
One night, Shalabha Arsha Baiju calls Manu and asks him to come home while her parents are away in Guruvayur. Manu visits Shalabha’s house with his friend Ambadi Althaf Salim. Unexpectedly, Indrasena Kurup Vijayaraghavan and his wife Susheela return and discover Manu with Shalabha. Fearing a public scandal, Indrasena Kurup reassures everyone that Shalabha’s marriage will soon be arranged with Manu.
The next day, Manu’s coworker, Assistant Engineer Jose Oommen (not linked here as he isn’t in the provided cast list), informs him that Meera is having an affair with a Christian teen named Disney James Niranjan. Manu and Jose visit Disney James, who runs a studio near Meera’s college, to learn more about her situation. Ushamma grows upset when she hears about Meera’s affairs, and Manu and Ushamma begin to take Meera’s actions seriously as she returns after a week-long college trip. Manu reviews Meera’s phone gallery and discovers photos suggesting another relationship, shocking him deeply.
Jose and Ambadi then approach Shalabha Arsha Baiju and urge her to uncover Meera’s true college crush in secret, since Meera’s family is planning a proposal for her marriage. Shalabha learns that Meera is in love with a young Muslim man named Anwar Shereef (not linked here due to the lack of a cast reference), which adds to the family’s urgency to arrange a match. Hearing about Meera’s other loves convinces Manu to push forward with a wedding arrangement for Meera as quickly as possible. With Jose and Ambadi’s help, Manu arranges a marriage proposal for Meera with a young man named Jeevan Raj Saiju Kurup.
Manu also informs Ushamma Bindu Panicker about Meera’s additional love affairs, stirring her anger and concern. Meera appears pleased when Manu and Ushamma tell her about the marriage proposal, but the situation remains tangled. The ceremony planning continues, though the family remains unsettled. On a Sunday, Jeevan Raj and his family come to Meera’s house to meet her and finalize the arrangements; Jeevan’s mother calls Meera’s neighbor Komala to inquire about her, and Komala vouches that Meera is a good girl, which reassures Jeevan’s family.
Meanwhile, Manu and Shalabha step outside and witness Meera’s students—one girl and one boy—who reveal that Meera has supported their relationship and promised to help them marry. This realization unsettles Manu. Late at night, Manu wakes up to drink water and overhears Meera on the phone, discovering that she has two more boyfriends, Vishnu Shine Tom Chacko and Mahesh. The next day, Manu and Ushamma search Meera’s room and uncover several SIM cards, deepening their worries.
Sree Shankar, who once visited Meera’s home to inspect their cow, arrives with his mother bearing a marriage proposal of his own, further complicating the choice before Meera and her family. Ushamma tells them that Meera’s marriage has already been fixed with another person and invites them to the wedding, even as Meera tries to temper her relationships with Disney James, Anwar, and Vishnu, explaining the marriage proposal. On the eve of the wedding, Anwar visits Meera, but Manu’s tension alarms him, and Jose consoles Anwar before returning him home. Meera’s quiet phone conversations continue to trouble Manu as wedding preparations proceed.
As the ceremony unfolds, Manu realizes that Anwar and Disney James, along with Sree Shankar, are present at the wedding. Despite the tension and concerns about possible trouble, the wedding proceeds without incident. After the wedding, a new revelation arrives: Bijukuttan, the bus conductor who often ferries Meera’s students, was also her lover for four years. This shocking disclosure adds another layer to the family’s concerns about Meera’s past relationships. Malu expresses admiration for Meera as a role model, which surprises Manu and Ushamma. Finally, on the night of the wedding, Jeevan Raj confesses all his secrets to Meera, closing the chapter on the wedding that had been fraught with complications and uncertain loyalties.
