Sundar Ramaswamy is a wealthy and ruthless NRI corporate raider in the United States, referred to as a corporate monster due to his ruthless business dealings. His imminent arrival in Chennai scares companies since they think they are a target for him. But he arrives to vote in the Tamil Nadu Legislative Assembly election. However, he finds that someone else has already voted in his place.

Sundar approaches the Tamil Nadu State Election Commission and demands a stay on the election result for his constituency, an annulment of the fraud elector's vote, and the ability to cast his vote legitimately. They agree with his opinion. He raises awareness among the public regarding fraudulent voting and finds that many people face a similar problem to his when trying to vote. M. Masilamani, the previous CM of Tamil Nadu, is re-elected, his daughter Komalavalli, and fellow politician and brother Malarvannan "Rendu" celebrate.

Sundar visits his family, rekindling with Nila, his brother's estranged sister-in-law. Meanwhile, Masilamani receives suitcases full of black money as he discovers a journalist, Muthukumar, hiding inside the luggage to record evidence of his corruption. Masilamani kills him and buries the case. Sundar's actions bring him into conflict with Masilamani and Rendu. Although Masilamani's party won the elections, the Election Commission annulled the result based on Sundar's plea to recount the votes, and the court decided to schedule fresh elections within the next 15 days.

After many assassination attempts on him by Rendu's henchmen, Sundar decides to contest the election against Masilamani as an Independent candidate and resigns from his company to avoid any conflict of interest. Initially unpopular among the masses due to his corporate background, Sundar delivers a speech detailing his rise from a humble fisherman upbringing to a business magnate and his struggle from poverty to riches, gaining massive support. Sundar and his supporters gatecrash an event involving the merger of Masilamani's party with the opposition. After Sundar confronts Masilamani regarding his silence on district-related issues, the police brutally beat up Sundar and his supporters.

At this juncture, Sundar realises that the entire political system in the state and country needs reform, so he decides to contest in all constituencies in Tamil Nadu along with his supporters. Sundar acquires video evidence wherein people who had attempted to expose Masilamani's corruption died under mysterious circumstances, and he plans to reveal it to the media to discredit Masilamani and have him arrested. Meanwhile, Masilamani's daughter Komalavalli, based in Canada] arrives in Chennai after discovering that her father and uncle have lost support due to Sundar. She decides to spoil Sundar's reputation and frame him as a corrupt and power-hungry person. Komalavalli orchestrates a car accident, planting a case of money stolen by a mysterious person, blaming Sundar for the accident, which causes him to lose considerable public support. Komalavalli furthers her agenda by killing her father with an overdose of diabetic tablets so that her party will gain sympathy votes. These crimes ensure that Komalavalli, the new Chief Ministerial candidate for her party, would likely win the election. On Election Day, Twitter messages generated from Muthukumar allege that Sundar has stashed black money in various locations, which further degrades Sundar's reputation. However, unknown to anyone, the tweets were sent by Sundar himself, as Muthukumar was one of those activists killed by Masilamani. Further messages lead to the discovery of Muthukumar's decomposed body, exposing Komalavalli's lies.

Meanwhile, Komalavalli finds out that her mother has decided to expose her role in Masilamani's death at the latter's memorial in front of the media later in the day. She arrives at the memorial with her henchmen to stop the expose, but Sundar subdues her henchmen, and her mother's confession is live-streamed, which ensures that the public support is back with Sundar. Sundar and his supporters win the election, while the police arrest Komalavalli and Rendu for various crimes. However, Sundar decides against becoming the Chief Minister and instead chooses one of his supporters, an honest collector, to be the next Chief Minister.

Real-life activists such as Kalki Subramaniam, Piyush Manush and Fatima Babu made cameo appearances as themselves in the song "Oru Viral Puratchi".

Sarkar received mixed reviews from critics with praise for Vijay's performance, plot, cinematography, action sequences, background score, soundtrack and social message, but criticised its screenwriting.

Anusha Iyengar of Times Now gave 3.5 out of 5 stars and wrote "Vijay's performance is far better and mature than any of his other performances. Jeyamohan, the writer of the film, deserves all the credit here for writing dialogues that only Vijay can pull off with that kind of impact and power." Sakshi Post gave 3.5 out of 5 stars and wrote "Sarkar has all the makings of a commercial thriller. You will see Vijay's signature dialogues which are whistle worthy and scenes with Murugadoss trademark. The film contains all the ingredients of a masala entertainer and keeps you engaged through the movie."

Sanjith Sidhardhan of The Times of India gave 3 out of 5 stars and wrote "The underlying message, strong performance by Vijay and also nods to several real-life incidents and people make Sarkar a smart and yet a bit stretched out." Gauthaman Bhaskaran of News18 gave 1.5 out of 5 stars and wrote "While Sarkar cannot be faulted in direction or mounting with some great action sequences, the plot has been written only for Vijay. There is really no place for a second character." Ananda Vikatan rated the film 40 out of 100.

Following release, the Government of Tamil Nadu accused the filmmakers and Vijay of inciting the people by targeting the ruling government in some scenes and defaming former chief minister J. Jayalalithaa by naming the main antagonist with her alleged original name Komalavalli. This led to numerous protests by AIADMK party cadre at theatres, where the film was screened, and vandalism of the banners of Vijay. AIADMK accused Sun Pictures, which is owned by Kalanithi Maran, who is the grand nephew of former Chief Minister Late Karunanidhi of DMK of targeting the government.

Several actors such as Rajinikanth and Kamal Haasan supported the filmmakers by raising the voice against the oppression of freedom of speech. They cited that a film must not be scrutinised even after the censor of the film by the Censor Board. Following the threat of lawsuits from the government, the filmmakers accepted to cut the scenes and mute references of Komalavalli in the audio track.

In October 2018, writer Varun Rajendran accused Murugadoss of plagiarising Sengol, a story that he had registered with the South Indian Film Writers Association in 2007. After K. Bhagyaraj, the head of the Association, concluded that Sarkar's script was not original, the matter was taken to court, where the judge directed both the parties to come up with an agreement for the scheduled release of the film. In the resulting agreement, the director admitted that the story of Sarkar was the same as of Sengol and that Sun Pictures agreed to thank Varun Rajendran and flash a message card for 30 seconds after the thank you note in the title card and also pay him ₹30 lakh (US$36,000) as compensation.
