Arundhati (Anushka) who is the great grand daughter of the Raja of Gadwal Mahasamsthan. Arrangements are being made for her marriage. Arundhati visits her native place before marriage. She receives a misleading phone call in her boy friend's voice asking her to come to the fort of Gadwal, where she faces a horrible experience. Learning the history from an aged servant maid Chandramma (Manorama), Arundhati comes to know that she is a look alike of her great grandmother Arundhati/Jejjamma (Anushka).
Jejjamma is an expert in painting, dancing and martial arts (essential skills for princesses). She has an elder sister who is married off to her father's nephew Pasupathi (Sonu Sood). Pasupathi a womaniser rapes the women he likes and kills those who objects. Jejjamma's sister commits suicide and the people of Gadwal thrash Pasupathi severely and tie him to his horse. Though Gadwal celebrates his death, he is saved by Aghoras (saints who practice dark arts). Pasupathi masters the tantrik arts and returns to Gadwal to exact his revenge.
Pasupathi unleashes carnage as he uses his powers to torture innocent people.Jejjamma performs a special dance mixed with martial arts to lull Pasupathi and then cuts off his tongue(thus ending the incantations) and pins his hands. She spares him from killing to prevent him from becoming a 'pretatma'(a demonic poltergeist). Pasupathi is buried alive in a tomb and powerful 'yantras'(defensive spells) with inscriptions from Vedas and holy scriptures are put on it to prevent the 'pretatma' from coming out. Jejjamma then as a final countermeasure sacrifices her own life by going through intense torture. She is killed and her body burnt and her relics are fashioned into a dagger. The one weapon that could destroy Pasupathi forever.
After this revelation through flashback, a worker in a trance, unknowingly breaks the tomb and releases the 'pretatma'. The revenge drama ensues again. Anwar (Sayaji Shinde) who treats patients through sorcery tells her that she is none other than Jejamma and asks her to fight Pasupathi. From the portrait of Jejjamma which was painted by Jejjamma herself during her last days before leaving the fort, Arundhati comes to know that her great grandmother had prepared a 'weapon' with her own bones and had kept it with some tribals. Anwar and Arundhati proceed to procure the weapon and in this process Anwar meets with an accident and falls off a cliff.
Arundhati, believing that Anwar is dead and is left with no option returns to the fort to surrender herself to Pasupathi, to prevent the death of her family members. Anwar, who survives the fall, collects the weapon and hands it to Arundhati. The Aghoras who crafted the weapon for Jejjamma tell Anwar that the weapon has to be soaked in Arundhathi's blood before it can be used otherwise it will not work. Arundathi tries to kill Pasupathi using the weapon without being soaked in the blood but it does not work. Before Anwar tells the secret about the weapon being soaked in blood, Pasupathi kills him. Without any option, Arundhati tries to kill herself with the same weapon and in the process the weapon gets soaked in her blood. The Dagger glows bright and the power incantations inscribed on it glow with energy and Arundhati kills Pasupathi
