The movie begins with Ramesh (Atharvaa) waking up in a hangover and remembering the events of the previous day. After a breakup with his girlfriend Madhu (Mishti), he is sad and drinks a lot along with his friend Nandhu (Karunakaran). On his advice, Ramesh calls for a female escort and sneaks her into his apartment. Ramesh has to step out of his house due to his neighbor Devi's (Devadarshini) emergency situation. He asks the escort, Nina (Anaika Soti), to wait inside his house, promising to come back soon. While he returns, he finds that she is dead under mysterious circumstances. Ramesh is shocked and tries to find details about her. He sees restaurant receipts in her bag, checks the CCTV footages, and finds that another man named Ravi (Prinz Nithik) had accompanied her prior to her meeting him. From her cell phone, he finds her house address, travels to Palakkad, and asks Nandhu to stay behind and guard the dead body. He is not able to find any information from Nina's family and leaves, but Nina's sister makes a call to Sekar (John Vijay) and informs him about Ramesh.

Sekar tracks Ramesh down and asks about Nina and Ravi. He says Ravi was a henchman and had usurped money and documents from the politician for whom he was working for. Ramesh escapes from Sekar. Nandhu calls him with information about a series of numbers that he found from Nina's purse and also says that he is hiding with the dead body in the attic because of Ramesh's intruding neighbors - Devi's father (Manobala) and husband Ram (Chetan), who came to use his gas stove for emergency purposes and would not leave. Ramesh goes to a railway station to find that the cloak room lockers are the series of numbers that Nina had noted down. He sees Ravi opening the lockers, beats him up, and asks why he killed Nina. Ravi says that he escaped with his boss's money and had picked up Nina to escort him. During his stay with her, fake police threatened and looted all the money. He finds that all of this was part of Nina's plan and that she had taken the money, hid it in the lockers and left for Chennai. Ravi found her, and after getting information about the money's location, he poisoned her drink as revenge. It is then that Ramesh had met Nina and she, unfortunately, ended up dying at his apartment.

After recording Ravi's confession, Ramesh strikes a deal with him that he should get rid of Nina's body from his house and takes him in his car. Ravi tries to escape, and after a chase, falls to his death. Disappointed, Ramesh returns to Chennai and plans to dispose of the dead body himself. Along with Nandhu, he drives Nina's body to the place where Ravi died. Keeping both of the dead people together along with the money, he informs Sekar of the whereabouts of Ravi, Nina, and the money. Sekar comes to the location, takes back his boss's money, and disposes of both Ravi and Nina's bodies.

Finally relieved of all the unwanted trouble, Ramesh and Nandhu get back to their homes in Chennai. Ramesh patches up with Madhu when Nandhu informs him that Sekar and his men died in a road accident. Ramesh and Nandhu are overjoyed because there is no living proof now of their unwitting involvement in Ravi and Nina's murders.
