The story starts with Jessica (Misha Ghoshal) confessing her sins to a priest at the St. Thomas Church in the outskirts of Chennai. The priest is then murdered while Jessica is abducted.

In the city, Assistant Commissioner Vetrimaaran (Arun Vijay) is celebrating his elder brother, Aravind (Amit Bharghav) and sister-in-law, Abhinaya's (Abhinaya) wedding anniversary. Everyone in the family is happy, except for Vetri's mother who berates Abhinaya for not bearing her a grandchild, despite many years of marriage life. However, after undergoing treatment by a famous fertility specialist, Dr. Tulsi (Kalyani Natarajan), Abhinaya finally becomes pregnant. While the rest of his family are in a celebratory mode, Vetri notices Abhinaya being moody most of the time.

Meanwhile, Vetri is put in charge of Jessica case assisted by Thirupathi (Thambi Ramaiah). Vetri suspects there is a connection between priest's murder and Jessica's disappearance. They visit Thendral (Mahima Nambiar), a teacher at the local preschool, who was the first witness to the corpse of the dead father. Thendral's family move out of the city's outskirts and unknowingly into the apartment right opposite Vetri's home. Only then does Vetri realize that her family is finding a groom for her and people will start questioning her morals if the police keeps on visiting her. Eventually, Thendral reveals that she saw two cars that day outside the church; one belonging to Jessica, and another black minivan driven by a group of mysterious young men.

Thendral is attacked by a group of thugs driving a similar minivan. She is saved by Vetri. After this incident, Vetri and Thendral start dating and fall in love. At around the same time, Jessica's body is found at a landfill site and it is revealed that she was pregnant at the time of her murder. Her husband, the director of a leading TV channel, simply claims that they have only recently tried to conceive.

Vetri's investigation soon leads them to a petrol station close to the church. The security cameras captured the men in the black minivan. At the same time, Thendral notices that the men are outside her apartment. She phones Vetri, who instructs her to shut all the doors and stay indoors. When Vetri shows up, the men have gone. When he goes home, he finds that his sister-in-law has hanged herself to death. The police concludes that Abhinaya committed suicide since there was no sign of intrusion. At her funeral, Abhinaya's mother reveals that she had asked her father for five million rupees a few days before. Thendral reveals that one of her doctor friends treated Aravind and Abhinaya and that Aravind is infertile, leading Thendral to theorize that Abhinaya might have been unfaithful.

While looking through his sister-in-law's postmortem report, Vetri realizes that her body contained traces of Clomiphene similar to Jessica's body. After talking to the coroner, Vetri learns there is a third young woman who matches this pattern.
