The story begins with Anandan, played by Prithviraj, who makes a maiden trip to his native village, Sivapuram. His purpose? To make good his promise to his recently deceased mother that he would dissolve her ashes in a river near Manthrikapura, a mystical garden, and light a lamp in Sivakavu, a strange and dark place in Sivapuram. Interestingly, Anandan, when he was young, had heard so many bedtime stories from his mother about the people and the places in Sivapuram. However, as soon as he lands in Sivapuram, Anandan finds out that what he heard and what he sees are two different things. To start with, the villagers warn him not to light the lamp in the forbidden Sivakavu. Since Anandan doesn't believe in anything supernatural he enters Sivakavu but only to find out that his life would never be the same again. Is there really anything supernatural happening to Anandan? If yes, then what is really happening and who's doing it? Is it Bhadra, his uncle's daughter and his lover? Or is it the enigmatic Digambaran, a mysterious person? Or is it Bama, Digambaran's lover? Or is it Chemban, her blind brother?
