Several members of Shweta's family are miffed at Senthil's "unauthorized" wedding, and his mother start's fearing for the newlyweds' safety when they move next-doors to their cousins. Soon after moving into their new house, strange things start happening, whether these are caused by the apparent ghost of a former occupant, Chandramukhi, or any one of the suspicious members of the extended family, will be looked into by "psychiatrist extraordinaire" Dr. Sarvanan.
