The film starts with a scene depicting many people being killed mysteriously. The film then cuts to Eswar Prasad (Jayaram) a politician who vows to resign from his post if the government fails to recover idols which were stolen over a period of 6 months. This wins the hearts of the masses. It also troubles his political rivals, who forge a plan to destroy his credibility with the help of CBI joint director Vaishnavi Natarajan (Asha Sarath) and Assistant Commissioner of Police Sampath (Murali Sharma). The two of them plan to interrogate Chanchala IAS (Anushka Shetty), a close confidante of Prasad who’s in jail for murdering her fiance, Shakhti (Unni Mukundan). To not arouse suspicion, they decide to shift her to Bhaagamathie Bungalow for the interrogation. The locals are afraid of the Bungalow and claim that it is haunted. As she’s left alone in the haunted house, she walks into one eerie room after another peering through dust-laden windows, rickety staircases and shows no fear of having to be in this strange place. A book and larger-than-life paintings foretell a story of Queen Bhaagamathie. Spirits take control of her and IAS Chanchala transforms into an unrecognizable person. How this impacts her and everyone around her forms the crux of the story. She is been taken mental hospital from there but Eshwar Prasad comes to visit her in the mental asylum. He tells that your acting as Queen Bhaagamathie was awesome then he tells thanks for saving me from CBI so he gives her 300 chores as a commission from where he had earned 1800 crores as black money. Whereas Vaishnavi Natarajan has found out all the valid points from the cooked up story of Chanchala and found that Eshwar Prasad is the culprit. In the Mental Asylum, after learning about Chanchala’s plan, Eswar Prasad tries to kill her. But, Sampath encountered him. Everyone was released and the culprits are arrested. When Sampath and Vaishnavi Natarajan questioned her why she had not answered their questions directly, she told them that people are not trustworthy. But, when she was questioned that whether she knew Arabic, She answered no which shocked them.
