Devi, a college student has a strange premonition one night of her sister being murdered. Her sister soon goes missing. After a few years, Devi meets and marries a rich businessman Ramkumar. Soon after, Devi has another vision of an unknown woman being murdered and seeks the help of her brother-in-law Raj to help her save the possible victim. Raj is reluctant to believe her story but assists her anyway. Devi also finds a decomposed body in the bungalow where she lives with Ramkumar, which she believes is her sister's based on her previous vision. Devi and Raj's investigations lead them to the museum where Devi's sister worked and a strange man who tries to assassinate them. Whether Devi's strange premonitions are true and whether she and Raj are able to trap the mysterious killer forms the rest of the story.

Sathyaraj's performance as a psychopath killer received huge acclaim and made him popular among audiences. The film became a milestone in Tamil cinema, with regards to "scene construction". The serial killers Auto Shankar and Jayaprakash were inspired by the film to commit murders. Sangeetha Devi Dundoo of The Hindu in her review of the Telugu film Tripura (2015) said that the idea of hiding corpses inside a wall is inspired from Nooravathu Naal.
