The film starts with a serial killer (whose face is hidden) stalking and filming a girl from outside her house. Later at night, he suffocates the girl by wrapping her head in plastic and tying her hands behind her. He then drags her to an abandoned football field, where he beheads her and sets her body on fire.
Later, the film focuses on Swapna, a single young woman and a talented game designer. She has a fear of darkness and suffers post-traumatic stress, moreso known as 'anniversary reaction', a condition which triggers unsettling feelings around the anniversary of a traumatic event. For Swapna, it is the horrific memory of her being raped in a dark room on last New Year's Eve.
Swapna's family has a traditional mindset that decent girls should not have tattoos or go out at night; to which she did not listen, and was later raped. Instead of comforting Swapna afterwards, they kept blaming the tragedy on her and not listening to them. As a result, Swapna left her parents and cut off contact with them. She leads a secluded life with Kalamma, her housemaid who stays with her. Her only solace is her love for gaming.
The new year is around the corner and Swapna suffers from PTSD a second time since last year after she has to enter a dark room, even with Kalamma being with her. She also feels a stinging pain in the tattoo area on her wrist from time to time, even though the tattoo (of a game life) is a year old. Before going to a doctor, Swapna meets Varsha, the tattoo artist whom she knows well, and asks her about it. Varsha nervously reveals that she made Swapna's tattoo with an ink mixed with a stranger's ashes by mistake, and later tried and failed to contact Swapna many times to inform her about it. She profusely apologises and tries to assure Swapna that it has nothing to do with the pain she feels, but Swapna angrily storms off. Swapna books an appointment for laser removal of her tattoo that day, but she is not able to go through with the procedure as the tattoo keeps stinging.
Later, Swapna goes to a nearby cafe to grab a coffee, but finds two men watching a video of her rape. Realising that the video has gone viral and consumed by grief and despair, she rushes out and tries to hang herself back at home, but is stopped by Kalamma. Swapna is taken to a therapy session where she is informed by Kalamma that her parents are coming to talk to her about the video. Panicked, Swapna immediately goes to the balcony and jumps off. She is saved, although her legs are broken, and she is now recovering on a wheelchair.
Weeks later, on New Year's Eve, a woman named Dr. Reena arrives with Varsha at Swapna's home. She tells Swapna about her daughter Amutha, a three-time cancer survivor and social activist for cancer patients who became an unfortunate victim of a serial killer. In Amutha's memory, Reena got the tattoo that Amutha wanted her mother to have, with the ink mixed with her ashes, which was also accidentally used by Varsha to make Swapna's tattoo. Reena comforts and encourages Swapna, saying that she feels her daughter is with her in the form of her tattoo, and will want Swapna to fight no matter what the outcome is.
Afterwards, Swapna cancels her second tattoo removal appointment. Beginning to accept her past and feeling optimistic, she decides to meet her parents the next day (which she had been deliberately putting off for the past few months), much to Kalamma's pleasant surprise.
Meanwhile, the same serial killer finally targets Swapna. At night, he kills the security guard and then Kalamma. Before he kills Swapna, she is shocked to see not one but three of the same tattoos on her wrist.
Swapna wakes up from the nightmare, only to find that there are two tattoos left on her wrist. Wanting to make sure it was all just a dream, she looks out the window with Kalamma to spot the security guard, but they are horrified to see his headless body on the ground. Fearing the same events about to happen, Swapna calls the police ahead of time and waits for them with Kalamma inside her room, but they are forced to leave when someone sets the room on fire from outside her window. In the living room, they see the serial killer waiting for them. He murders Kalamma, but two police officers who had just arrived are able to spot the killer from outside the window and shoot him.
Outside the house, Swapna sees the curtain being closed by the killer inside. Assuming him to be still alive, Swapna alerts the officers. When one of them searches inside, he finds the body of the killer gone. He immediately orders his subordinate to take Swapna to the police station while he stays behind and calls for backup. As the vehicle is driving off, Swapna is shocked to see in the rear view mirror not one but three killers with the head of the officer, waving her goodbye with the hand of the previously dead killer sitting on her wheelchair. She looks behind and, to her horror, sees the vehicle on fire. She cries to the officer to stop the car, which when he does, instantly makes the vehicle explode.
Remembering her trauma and Reena's words, Swapna awakes again from the nightmare with her last life remaining, only one tattoo. She struggles for a bit but doesn't switch the light on this time, overcoming her fear of darkness in the process and not bringing her awareness to the killers's attention, who had just beheaded the security guard. The three men take their positions at their own pace, one outside the front door, one outside Swapna's room window and one going to the terrace. During this extra time, Swapna, this time more calm, calls the police and then plans with Kalamma on how to counter the situation. She switches off the light of the whole house, which stops the killer outside her front door from recording anything inside, confusing him. She and Kalamma then manage to burn the other killer outside her room window to death, just as the police arrive.
