Omprakash, a tattoo artist, purchases a studio on the outskirts of Chennai in order to expand his career. He meets up with his college crush Nila, a vampire who tries attack him and stops after she recognizes him. Love blossoms between them both, and Nila reveals how she was turned into a vampire by Alex, who wants to turns the human-dominant civilization into a vampire-dominant one. A group of people called slayers are trying to demolish these vampires since they are considered bloodsucking animals.
One day, Nila introduces Om to her best friend Meera (a 125-year-old vampire), who rejects her relationship with Om since he is a human. On the same night, Alex catches Nila red-handed with Om, and they are both assaulted by Alex and the rest of the group until they are rescued by slayers, who burn Alex and his group by a new weapon. Om takes a promise from Nila not to turn him into a vampire; in turn, he promises her to turn her back into a human. After many trials, he arrives at the doorstep of Devi, a sorceress whose blood can turn vampires back to humans, and she herself becomes a vampire and turns back to normal after reading certain scriptures. Devi refuses to accept Om's pleas since she feels herself losing her control after her last encounter with a vampire in which she loses control and kills her own disciples.
A completely shattered Om is blackmailed by a goon who tries to kidnap his assistant Poonkodi. Suddenly, Nila emerges from nowhere and kills the goon. Om loses his temper and asks Nila to not be like a monster and get lost from his life. The next day, Inspector Jamal, a slayer, investigates the case and finds out Nila to be a vampire. Nila hides in Meera's home and stops drinking blood because of Om's accusations. Om becomes more concerned about Nila and goes to rescue her when Meera was caught by the slayers. He confesses to Nila that he was afraid to lose her and is deeply in love with her. Suddenly, the slayers attack them, and Nila hypnotized one of them to sleep, while the other was hurt by Om.
Nila becomes very weak because of her blood strike. Om offers his blood, but she refuses it because of her promise. Om takes Nila to Devi, who changes her mind and decides to help Nila while preparing for the arrangements. Jamal attacks them from outside the home. Devi asks Nila if she had hypnotzed Om into loving her. Nila reveals that none of the vampires are able to hypnotize Om. Jamal shoots an arrow which strikes Om. Devi informs to an almost-dying Om that he is just like her and his blood can turn Nila back to a human. Upon hearing this, he asks Nila to suck his blood, and she obeys. Jamal breaks into Devi's house and is shocked to see Nila, who is now a human. The series ends by revealing that Om has become a ferocious vampire.
