NRI Siddharth Chaturvedi and his wife Avni return to Siddharth's family's ancestral Varanasi palace while disregarding warnings of a curse and paranormal phenomena. Soon enough, inexplicable events begin occuring, which forces Siddharth to consult the eccentric psychiatrist Aditya Shrivastav to help solve the mystery.
A young couple, Ganga and Nakulan, arrives at the ancestral home called Madampalli of the latter. Hailing from a family that follows tradition and superstitions, Nakulan's uncle Thampi objects to the couple's idea of moving into the allegedly haunted mansion, which Nakulan ignores. The couple moves in anyway following which seemingly supernatural events begin to happen.
Creepy happenings in an abandoned mansion are attributed to the ghost of an ancient courtesan, back for revenge.
