S Saraswathi

Lakshmi (Varalaxmi Sarathkumar) works as a government nurse and lives with her daughter Saraswathi. Lakshmi drops Saraswathi off at school for the Independence Day celebration, which is also Saraswathi's birthday. Lakshmi comes to pick up Saraswathi in the evening, but the school says there is only one girl named Saraswathi, but it is not her daughter. The police sub-inspector (Murali Sharma) comes to investigate, but there is no evidence that her daughter studies at that school. The next day, Lakshmi goes to the police station and says that her daughter was abused by the principal and other staff, which resulted in her daughter's death, and she buried her in the cemetery. When the police reach the burial site, they do not find Saraswathi's body, and the police say they cannot proceed with the case because there is no evidence.

Lakshmi hires the lawyer Ramanujam (Prakash Raj), who fights for justice and truth. Ramanujam decides to take up the case and try to make a case even though there is no evidence, but Saraswathi says that these are not the people who abused her daughter. After a few months, Lakshmi kills a judge, a district collector, and a top police officer. She surrenders and informs the judge that those people have abused her daughter. Chief Justice Uma Maheswar (Rao Ramesh) orders Ramanujam to investigate the case thoroughly and provide the proper details. Ramanujam reaches out to Lakshmi's husband Aditya (Jiiva); the couple lives separately. Aditya informs that they do not have a daughter and says Lakshmi cannot have kids. He informs Ramanujam that the evidence picture is Lakshmi's childhood photo. Ramanujam reaches out to Anthony (Nassar) to understand what is happening to Lakshmi and perform hypnosis on her to get the truth out of her.

Lakshmi is actually Saraswathi, and her parents are Lakshmi (Priyamani), and Prabhakar (Kishore), and an abuse incident happened to her. While in prison, she also kills the minister who attends the Independence Day celebration. Ramanujam pleads to the judge that she is suffering from a fantasy disorder and asks for a reduction in her prison sentence. She is admitted to a mental asylum, and it is later revealed that Aditya and Lakshmi planned the whole thing to take revenge.
