The film begins a few hours before a public speech by the Chief Minister of Kerala, C. K. Joseph. A mysterious man known only as “The Commoner” arrives at the venue in an ordinary vehicle and enters the room where party workers are resting and refreshing themselves. Blending in easily, he spends his own money at a nearby hotel to pay for food ordered by the party workers. He casually interacts with them and later buys a tender coconut drink for the Chief Minister. During his first public speech after being declared Chief Minister, Joseph suddenly experiences severe abdominal discomfort caused by the drink given by the Commoner. Instead of admitting that he urgently needs to use the restroom, party members claim that the Chief Minister is suffering from chest pain and insist that he be rushed to the hospital. At that moment, the Commoner and a few party workers arrive in an Ambassador car and take Joseph inside. While on the way, the Commoner suddenly kicks the party workers out of the car and drives off, successfully kidnapping the Chief Minister. A Special Investigation Team (SIT) is formed under
Commissioner Dev G., assisted by
ACP Ashkar Ahammed and Noble, son of Joseph and an officer of the National Efficiency Agency (NEA) from Chennai. Soon after, Mahi, a blind accomplice of the Commoner, surrenders himself to the authorities after presenting them with his own image as proof of involvement. Meanwhile, the Commoner, along with Vaavamani, takes Joseph to a secret hideout. At the hideout, the kidnappers initiate an unusual campaign. They ask the public to write letters describing their grievances and place them in a designated vehicle so the Chief Minister can personally see the problems faced by ordinary citizens. They argue that politicians only listen to people during elections. The public responds enthusiastically, filling the vehicle with thousands of letters. Historian Sivankutty later informs Noble that the kidnappers are deliberately trying to gain public sympathy and support. He then turns himself in as another accomplice of the Commoner. During interrogation, Mahi, Sivankutty, and another accomplice named Sijo reveal a shocking truth: ACP Ashkar is secretly part of the Commoner's gang. When the kidnappers attempt to retrieve the vehicle filled with public letters, the police launch a chase. During the pursuit, Ashkar openly joins the Commoner, revealing that he is actually the Commoner's close childhood friend. Together with their ally DJ Torpedo, the Commoner and Ashkar overpower the police forces sent to capture them, humiliating both the government and the police department. Noble later learns about the Commoner's past through Godson Ancharakandy. The Commoner had been orphaned at a young age and suffered severe psychological trauma, which led to him being admitted to a mental hospital. After escaping, he fell under the influence of the notorious gangster “Ghilli” Bala, eventually becoming his trusted right-hand man. Together they began intercepting illegal gold and weapon smuggling operations run by the Oscar Brothers, reselling the seized goods and amassing great wealth and power. Eventually Bala stepped away from the criminal world, leaving the Commoner in charge. As the investigation intensifies, Noble discovers that the Commoner communicates with the public through a group of local boys known as the “Thalapathy Boys.” Attempts to interrogate them are repeatedly blocked by the cunning lawyer Advocate Mukundan Unni. Meanwhile, Dr. Frederick D’Souza reveals that the Commoner suffers from a severe psychological condition that causes him to react extremely when emotionally disturbed. Using this information, Noble tracks down Ashkar and eventually captures Vaavamani and Madhu, a media personality who publicly criticizes the police investigation while secretly boosting the Commoner's popularity through his television channel. Through Ashkar, Noble also learns about an elaborate plan by the Commoner to attack a police station using a group of elderly men in order to rescue his captured allies. However, the plan fails when Noble kills Mahi during the attempted escape.The conflict escalates further when the Black Force locates the Commoner's hideout and launches a massive pursuit operation. With Joseph still held captive, the Commoner wages war against the forces using an armored combat vehicle supplied by Ghilli Bala. Bala himself joins the fight alongside the Commoner deep within the forest. In the final confrontation, the Commoner reveals the true reason behind the kidnapping. Years earlier, during the funeral of the Commoner's mother, Joseph had made humiliating and lewd remarks about her. Later, at one of Joseph's legislative assembly victory rallies, he prevented the Commoner's father from receiving urgent medical help, which ultimately led to the father's death. At both moments, Joseph wore a disturbing grin that haunted the Commoner throughout his childhood. The Commoner's ultimate goal is not simply revenge, but to wipe that grin from Joseph's face forever. Although Noble eventually rescues his father, the Commoner succeeds in exposing Joseph's corruption through secret files released by Godson. Joseph's reputation and career are destroyed, and the smug grin finally disappears from his face. In doing so, the Commoner fulfills his father's wish that he one day become a powerful and influential figure. Before disappearing, he warns Noble that he will one day seek revenge for Mahi's death. In a post-credits scene, the Commoner is revealed to be Ram Damodar, also known as “Radarr.” While in custody, he is readmitted to the same mental hospital where he once lived. There, assassins sent by the Oscar Brothers attempt to kill him, but Ghilli Bala intervenes and saves him. Furious, one of the Oscar Brothers vows revenge against both Bala and Radarr. ==Cast==
