In 1920
Srikakulam, a group of tribals along with their king, try to stop the massacre of their people by the
British, for mining gold. However, they are unsuccessful in doing so and their king dies without telling the survivors of the massacre about a prophesied descendant of their tribe. In 1991,
Constable Byreddy Surya "Suri", a young and aggressive, but well-mannered police officer who, after being separated from his elder brother, Siva, during their childhood for killing their abusive father, is recruited by a RAW handler, Jayaprakash 'JP', to go on an undercover mission. His objective is to infiltrate the heavily fortified island off of
Sri Lanka, known as "Divi", in the midst of the
Sri Lankan civil war and obtain details about a huge consignment of arms and gold coming from Hong Kong, just a few months after the
assassination of Rajiv Gandhi. However, Divi is ruled with an iron fist by Odiyappan, who is part of the Sri Lankan cartel and comes from a Tamil-speaking family. Suri is shocked to know that his long-lost brother, Siva, is the leader of the descendants of the tribe from 1920 who have relocated to Divi to escape from the British. He begins his mission by instigating a brawl during a temple festival and getting himself arrested and sent to
Jaffna prison, a place notorious for its brutal and lawless conditions. Upon his arrival, the two brothers, now on opposite sides of a brewing conflict, are reunited under tense and dangerous circumstances. Suri's mission becomes more complex as he struggles to balance his loyalty to his country and newfound connection with his brother. He gains favor within the prison's hierarchy and the trust of Siva. Siva and his gang manage to get bail and also post Suri's bail; they take him to Divi where Suri slowly begins to understand the real stakes of his mission after witnessing what the residents of Divi go through with Odiyappan and his younger son, Murugan. He frequently reports to Dr. Madhu, an Indian doctor who is also a spy, about his mission. In a critical moment as part of Siva's gang during a smuggling operation, Suri is forced to leave behind a consignment of gold during a chase in the mangroves of Jaffna by the Sri Lankan navy. In a cartel meeting with Siva and his gang, Murugan grows suspicious of Siva and his people due to the navy's appearance during their smuggling operation. Realizing the danger of the fallout and his concern for the residents of Divi, Suri promises to bring back the gold consignment from a naval base. His success in this mission makes him a celebrated figure amongst the Divi's residents and strengthens his equation with them. However, Siva comes to know of his true identity of an Indian police officer in the process. Murugan's
paranoia intensifies after he murders his own father, Odiyappan, and realizes there is a mole within the ranks of the cartel. He invites the people of Divi along with Siva and his family, to witness the last rites of his father and feast at his house. However, one of Siva's deputies, Singha, remains wary of Suri and promises to look into his background, leaving Divi in the process. Meanwhile, it is shown that Jayaprakash has planted many spies in Divi and the Sri Lankan cartel, with Murugan's deputy, Selva, being one of them. Murugan begins to believe that Suri is the traitor after Selva hands over circumstantial evidence to a senior cartel member present there, Saravanan, proving that one of the Byreddy brothers is a spy. After a confrontation with the cartel members, Siva falsely admits himself as a spy and is mercilessly killed by Murugan along with many of his people, including his wife. On the other hand, Suri drinks alcohol for the first time in his life and admits to Madhu that it was he who killed his and Siva's father, and that Siva took on the blame for it. He realizes that the life he has been living belongs to Siva, and he should be in Siva's shoes instead. He learns of his brother's fate and Murugan's massacre from Madhu the following morning. Driven by an amalgamation of fury and grief, he unleashes his full potential to avenge Siva and the residents' deaths and liberate the remaining people of Divi. A fierce battle ensues where Suri confronts and kills Murugan, fulfilling the prophecy that he is the
reincarnation of the past king. He then assumes leadership of Divi, as king for the people in need of a savior. In a twist, Sethu, Odiyappan's elder son and Murugan's elder brother, arrives in Divi to avenge his kin, while Singha finally reaches Suri and Suguna's house in Ankapur and finds a photo of Suri in his police uniform, hinting at a sequel. == Cast ==
