Devika wakes up from sleep and appears confused. She checks for body injuries and finds an earring missing. She cannot remember what happened the day before. She is a school teacher in charge of athletics, and her colleague assures her that she is just tired because the school has been hosting a sports meet over the last four days. Her husband, Sujith, is a male nurse, and together they have been trying to conceive for a long time.
Devika finds out that she is pregnant, but she is still traumatized because she was raped by some college students during the last school meet. She hides that information from her husband. She looked for CCTV footages of what happened but the cameras were not working during that time. She searches porn sites for videos but does not find any. As a last step, she visits one of the students' homes and cleverly keeps her phone on recording mode in his car. From the conversations he has with his friends, Devika understands that they still have video recording of her rape.
Sujith gets to know that Devika is pregnant from the lab report. He visits her doctor who asks Sujith why they are opting for abortion. Sujith confronts Devika and Devika admits that she was raped. Sujith gets angry that the fetus might be one of the rapists and he does not want to father it. Devika wants to file a police complaint, but Sujith discourages saying the family name will be ruined.
Sujith's mother, Kalyani, a veteran comrade, gives her encouragement to take revenge on the students. Devika goes in search of them and finds the leader of the gang working in a food delivery service in Kochi. Kalyani recommends a police informant to her and that he will help her. Devika meets the student and pretends that she is sexually interested in him. He invites Devika to a hotel in a remote place. There she finds all the students in the room who although deletes the video and destroys the memory card, insults and abuse her and says they don't want to see her again. Devika then locks the door and reveals that she is trained in martial arts and fights all the students with the help of her friend. They attach mock bombs to the kids and scare them to death but leave them alive. Finally, she reveals to Sujith that she does not need him in his life, but she will keep the baby.
