Plot Tamil Nadu Police Inspector Vijay Prakash is obsessed with reviving his reputation, which was tarnished 32 years earlier when his father, former RAW agent Chandra Bose, was branded a national traitor. The social disgrace led Vijay's entire extended family to commit suicide, leaving Vijay to be raised by a sympathetic police officer, Paavadaisaami. Vijay woos his childhood friend, Advocate Shalini, who represents social activist Sameera Thomas in court. Sameera is petitioning against "One India One Pipeline", a project spearheaded by National Security Advisor Maharaj Rathore's private water company to control India's potable water supply.

After the court rejects the petition, a classified file containing details of 1980s RAW agents is stolen from a secret vault in Rajaji Bhavan. Deducing Sameera took the file, Vijay tracks her down with the help of her son, Timmy, but later finds her murdered; her death is staged as a suicide, and she is framed as a traitor who stole and sold state secrets. Refusing to accept this, Vijay discovers that Timmy suffers from Sarcoidosis due to BPA in packaged water, which caused her to actively protest against companies ignoring safety rules. He further learns that Sameera was murdered for refusing to disclose the location of a secret operative known as "Sardar". He accesses her laptop, uncovering her research that the "One India One Pipeline" project aims to monopolise the nation's water supply.

Vijay and Shalini learn Sameera was scheduled to meet Agent Karapanpoochi, who provided her with the key to the classified file. They locate Karapanpoochi at a railway station, but an unknown assailant kills him during a chase. Inspecting his belongings, Vijay finds the address of a prison in Chittagong, Bangladesh, to which a red letter was previously sent by Timmy. The letter contains a covert "Code Red", alerting RAW Chief Chandra Mohan that an unidentified inmate held in Bangladesh for 32 years is actually Sardar. Rathore learns of this and instructs the NIA to have the inmate killed, but a sympathetic guard alerts Sardar, enabling his escape.

Vijay retrieves the stolen file from a hidden bunker, defeating an assassin sent to intercept it. Through the documents, Vijay and Shalini learn his father's history.

In 1985, Chandra Bose operates as a RAW agent codenamed "Sardar" while maintaining a cover as a stage actor. He marries his cross cousin, Indhrani, who secretly knows of his intelligence work. Following a border water-poisoning incident, Sardar's trainer Rathore and Agent Victor deploy him to infiltrate a Pakistani army camp. Sardar retrieves a Chinese document revealing that China conspires to force India into adopting the pipeline project by poisoning local water sources, aided by an Indian mole codenamed "Laughing Buddha". Sardar identifies Advisor P. K. Abraham as the mole. Rathore instructs Sardar to assassinate Abraham, proposing to temporarily brand him traitor until Abraham's treason is proven. However, consumed by greed, Rathore frames Sardar permanently and joins the Chinese syndicate as the new "Laughing Buddha". Oblivious to Rathore's intentions, Sardar surrenders to the Bangladesh Coast Guard to hide, while Rathore resigns, and leaves Sardar's family to face disgrace.

In the present, learning of Rathore's betrayal and his family's fate, an enraged Sardar tracks Victor. Paavadaisaami is forced to help RAW detain Vijay to lure Sardar, while Shalini visits Victor, who has been sheltering Timmy. Sardar infiltrates RAW headquarters disguised as Victor, using Chandra Mohan's biometrics to access the central vault. Trapping him in the vault, Rathore reveals to Sardar that he personally murdered his family, staging it as a mass suicide after Indhrani overheard his plot, to ensure Sardar remained framed as a traitor. A detained Vijay overhears the conversation.

Outraged, Sardar drives a truck loaded with reactive Sodium into Rathore's central water plant of the project, asking Timmy to remain outside. While Vijay assists by subduing Rathore's mercenaries, Sardar drives the truck into the water tanks, causing a massive explosion that destroys the infrastructure and kills Rathore. Following the incident, Sardar reunites with Vijay and dissuades him from clearing his name publicly, arguing that exposing state corruption would undermine public trust in the government.

The government clears Sameera's name and cancels the pipeline project. Vijay is suspended from the police force for failing to capture Sardar; however, Chandra Mohan, who has discerned the truth about Rathore, reveals he orchestrated the suspension to covertly recruit Vijay into RAW for an overseas assignment in Cambodia.

Cast

Production Development In late-December 2019, it was reported that Karthi, who was filming for Ponniyin Selvan: I and II at that time had signed a new project with P. S. Mithran and the production would commence only after his commitments for the two-part series. However, production of the two-parter was halted due to the COVID-19 pandemic lockdown in India which led to Karthi prioritizing on other projects. On 14 November 2020, coinciding with Diwali, the production company Prince Pictures officially confirmed the project.

A puja ceremony was held at the office of Prince Pictures with the actor and director being present. Mithran renewed his norm technicians—cinematographer George C. Williams, editor Ruben and stunt choreographer Dhilip Subbarayan—while G. V. Prakash Kumar was assigned as the music composer and K. Kadhir served as the art director. The film's title Sardar was officially announced on 25 April 2021.

Pre-production Mithran wrote the initial script during the COVID-19 lockdown period, with fellow co-writers M. R. Pon Parthiban, Roju, Bipin Ragu and Geevee providing additional inputs. In an interaaction with Srivatsan S of The Hindu, Mithran admitted that he wanted to make a "suave" spy film like the James Bond and Mission: Impossible films, but the principal characters in the films—Bond and Ethan Hunt—did not have a family and are emotionally detached, which led to the question "Why are spies in movies that cold? Should they be cold? This film is such an exploration. I’ve balanced out my ambitions with the palatability factor." Pre-production for the film commenced in late-November 2020 and continued through early April 2021, with reports suggesting that filming would commence after the release of Karthi's Sulthan (2021).

Casting

Karthi was reported to play dual roles in the film: one being the police officer and the other being the agent. It was the second time the actor played dual roles after Siruthai (2011). For the titular character as the agent, Karthi was seen sporting around 15 different makeovers; Mithran clarified that "every single makeover has a purpose. The film is about a theatre actor who can play several characters in a single play. I wrote Karthi’s character with this description: someone from the audience goes and tells Karthi’s character that they really enjoyed the play and thought he did a terrific job in five disguises. Then the Karthi character would say: 'No, I actually had 11 disguises in the play.'"

In April 2021, Raashii Khanna and Rajisha Vijayan was announced as the female leads; the latter, in her third Tamil film after Karnan and Jai Bhim (both 2021). Simran was further signed to play an important role, and Chunky Panday was cast as the main antagonist, marking his Tamil cinema debut. In March 2022, Simran opted out of the project due to scheduling conflicts and Laila signed the project the same month, returning to films after a 16-year hiatus. Balaji Sakthivel, Rithvik, Munishkanth, Yugi Sethu, Avinash Yelandur, Yog Japee, Mohammad Ali Baig amongst others were cast in supporting roles.

As each day of shoot in these countries, accounted to around , the team had nearly spent for the particular schedule. The team initially planned to shoot combination sequences between Karthi and Panday, but as Karthi was on a vacation during that time, Panday's portions were shot first.
