Plot
In 1983, Deva Dutta is a journalist from Hyderabad who converses with a senior citizen to learn about the history of Kollapur. Opposing the incorporation of Hyderabad into India after independence of the country from British Raj in 1947, the Nizam sent Razakars to ruin Hindu provinces and temples. In such scuffle, Raja Balakishan Rao, the generous aristocrat of Kollapur, had died due to the betrayal of his greedy commander Narsappa. After the state successfully became a part of India in 1948, Narsappa desired to contest in the general elections, but Raja Balakishan Rao's confidant Raja Ratnam advised Raja Balakishan Rao's wife Rani Ramachandramma to participate in the elections for social welfare.
Rani Ramachandramma subsequently wins and establishes several institutions like schools and hospitals for Kollapur. Taking advantage of Raja Ratnam's strained relationship with his son Perumaallu, Narsappa looted the treasury and set fire to the palace that apparently killed Rani Ramachandramma, Raja Ratnam, and the former's child. As a result, Narsappa became an MLA and established his control over Kollapur with his iron fist. In the present timeline, a fire breaks out at a liquor store that was evidently created to kill Narsappa's tender-hearted brother Sekhar Babu, whose burning corpse is found hanging to the tree. Believing that Perumaallu had murdered his brother due to their recent fall out, Narsappa wreaks havoc trying to find Perumaallu, who goes into hiding.
The police Department assigns Kalki IPS in charge of Sekhar Babu's murder case, while Dutta seeks to help him. They find out that a murder attempt on Sekhar Babu was staged a few days ago during Bonalu with a poisoned arrow, but Sekhar Babu's friend was shot inadvertently. Upon perceiving from an Ayurvedic doctor who treated Sekhar Babu's friend, they learn that the poison was extracted from a breed of snake found in Nagulakona, a hamlet that was destroyed to due to recent forest fire killing everyone in it, Dutta and Kalki leave to Nagulakona. Touring the burnt area of Nagulakona, Kalki realizes that the fire was not natural but engineered to kill the villagers.
Meanwhile, Narsappa abducts a tribal girl named Palapitta to make her his concubine. She makes excuses to protect herself temporarily, but continues to stay at his residence. Dutta learns that Kalki was in love with Padma, who is the head doctor in the local government hospital, but their relationship was strained as Kalki inadvertently killed Padma's father, a school head who was housing Maoists. In a parallel story, Kalki and Dutta learn about a love story between Sekhar Babu and a Muslim graduate Asima Khan, who is the daughter of Adv. Kabir Khan. They meet the latter and learn that Asima wanted to establish a boating business that helped people travel to Srisailam from Kollapur through the river in the forest.
When Sekhar Babu helped her through this and succeeded in establishing the business, the boats carrying 60 people were ambushed and everyone was brutally murdered. As Asima was blamed for the incident due to her religion, Kabir migrated to another village with her and believes that Sekhar Babu was also murdered for trying to crack the conspiracy. Kabir Khan states that there is an eyewitness for the massacre, who is not ready to arrive in court. It was overheard by one of the servant in Kabir's house, where the information is passed to Narsappa Kalki and Dutta meet the eyewitness Sambasivudu, a saint dedicated to the service of Hanuman, and learn from him that a few masked men had ambushed the boats and killed the people by drowning them to death. However, Sambasivam does not wish to testify against the masked men.
Meanwhile, Narsappa tries to kill Asima with his henchman, but Kalki comes into her rescue and suspects that Narsappa is behind Sekhar Babu's murder as Sekhar Babu is Narasappa's stepbrother and also was very popular in the village. Narsappa leaves them without saying a word. Later, Kalki reveals to Dutta that he lied to Narsappa to save Asima. There is a myth over the village that Rani Ramachandramma's spirit haunts the burnt palace, but Kalki and Dutta discover that the owner of the liquor store, where Sekhar Babu died had been masquerading as the ghost to evade a murder attempt on him from Narsappa. From the store owner, Kalki perceives that a few hours before he died, Sekhar Babu gifted a watch to the owner for vacating the store so that he could enjoy alone with his friends.
From a portrait in the palace, Kalki and Dutta realize that Sambasivam is none other than Raja Ratnam, who apparently died in the fire, but actually escaped. They go to meet Sambasivam alias Raja Ratnam and perceive that he is hiding Perumaallu from Narsappa. Sambasivam expresses his regret for not being able to save Ramachandramma and her son and for not bringing up his son in a proper way. However, Kalki convinces them to come with him. At the same time, they are ambushed by the skeleton masked men who wound Sambasivam, while Kalki manages to rescue Perumaallu. Before dying, Sambasivam tells Kalki that the recurrences are not coincidental, but are due to karma.
Kalki bashes them and apprehends all the masked men, which reveals to familiar people in the village, including the servant of Kabir Khan's home. When Kalki tries to grab the man's testimony about Narsappa's role behind the so-called forest fires in Nagulakona and the massacre of boats, the man uses Padma as a human shield but is shot to death by Kalki, where Padma realizes that Kalki was not wrong. When the tribal man (who attempted to murder Sekhar Babu with the poisoned arrow) tries to kill Perumaallu, Dutta and Kalki apprehend him and learn from the person that he is a native of Nagulakona, where the people were brutally murdered and burnt to death by Narsappa, Perumaallu and other masked men. The tribal man decide to seek vengeance against Narsappa and his family, where he attempted to murder Sekhar Babu.
Perumaallu escapes from the custody, while Kalki meets his superior and divulges that Nagulakona was an obstacle for Narsappa to operate his red sandalwood smuggling business, due to which he got rid of the villagers and staged a forest fire. The boats were going through the same river route, and Narsappa felt the boating business to be a hindrance for his men to chop the sandalwood and massacred the boats, framing it on Asima. Kalki arrests Narsappa, revealing the fact that Palapitta is an undercover cop. On the way, Perumaallu shoots Narsappa and Kalki encounters the former, closing the case but is slightly injured. Dutta receives his promotion for covering the incident.
In the hospital, Asima meets Kalki, but Padma misinterprets their conversation and presumes that they are having an affair. Asima reveals to Padma that Kalki was the person who murdered Sekhar Babu as Sekhar Babu was a helping hand to his brother in his crimes and was not like the villagers thought of him. When Asima learnt about Sekhar Babu's involvement in the boats massacre when she met him at the liquor store, she tried to escape, but was caught by Sekhar Babu and his friends, who attempted to molest her. Kalki (who was roaming around in dejection as Padma broke up with him on the same day) arrived to protect her and tied Sekhar Babu and his friends to the tree, but Sekhar Babu's lighter slipped from his pocket and the tree, wet with arrack is burnt, which kills everyone tied to the tree. Realizing Kalki's true nature, Padma reconciles with him.
Dutta overhears Asima and Padma's conversation and tries to inform it to Kalki's superior but realizes that the police department sent Kalki to eliminate Narsappa and Perumaallu for their crimes. Dutta tries to inform it to the editor but is interrupted by a woman searching for Kalki's room. After she leaves, Dutta realizes that the woman is Ramachandramma, who was presumed to be dead along with her son. Dutta follows her to Kalki's room and realizes that Kalki is her son. Dutta realizes that karma led Kalki to Kollapur, where he avenged the injustice done to his village as a royal descendant unbeknownst to himself. The information is also meant by Sambasivam, who died protecting Kalki after seeing the chain belonging to royal family with him. Kalki is discharged from the hospital and leaves with Padma, Ramachandramma and his assistant.
