Plot
Kannan, a charismatic but enigmatic man, arrives in Malaysia to escape a shadowy criminal past, adopting the alias "Bolt" Kannan. He befriends Arivu, a ragpicker who poses as a wealthy businessman to impress his girlfriend, Kalpana, providing comic relief. Kannan meets Rukmini, called Rukku for short. She is a determined young woman working odd jobs to reclaim her late parents’ house from her abusive stepfather, Rajadurai, a corrupt police officer. Meanwhile, Rajadurai coerces Preethi, a young woman into having sex with him in return for not posting her intimate video online without her consent.
Kannan and Rukku get romantically involved. As Rukku in a financial predicament due to Rajadurai, and is also under threat of losing her job, Kannan decides to get a loan of RM 1,000,000 to help her. Together with Arivu, he goes to a dockyard owned by Dharma, a ruthless loan shark. Kannan joins a table of poker and expertly starts to rack up his wins. As the stakes rise, Dharma himself joins the table to challenge Kannan and wins by rigging the game. Now stuck with his own debt on top of Rukku’s financial crisis, Kannan decides to rob an armored truck delivering cash to the bank. Kannan fights and evades the police, stealing RM 20,000,000 (₹403,927,600 (US$4.8 million)). The police arrest Dharma after finding his partial fingerprint on the magazine from the gun that Kannan used in the heist. A flashback reveals that Kannan stole Dharma's gun from his club. Coincidentally, Kannan then finds out that he has won RM 20,000,000 from the lottery as well. Kannan and Arivu request Kalpana to collect the lottery in order to not be seen in the public eye in the aftermath of the heist. Kalpana overhears a conversation between Kannan and Arivu about the bank heist, and they are forced to show her the stolen money.
Kannan books Rukku a Rolls-Royce Phantom, buys her a dress, and invites her to a hotel. He decides to settle Rukku's debt by paying RM 1,000,000 (₹20,196,380 (US$240,000)) from his lottery winnings, to Rajadurai at the hotel. However, Rajadurai recognises Kannan as the culprit behind the bank heist, because Kannan had shot him in the leg during the robbery. Rajadurai talks with Kannan privately and reveals that he wants to keep the money, the house and Rukku since he has desired her from a young age. Assuming Kannan has managed to convert all the stolen money into unmarked bills, he takes the RM 1,000,000 and tells him to deliver the rest to his house. Soon, Kannan and Arivu are thrust into a chaotic chase, pursued by Dharma’s goons after Arivu reveals in fear that Kannan framed Dharma and stole the money. Dharma also tells Kannan that he wants all of the stolen money.
Rukku finds the stolen money at Kannan’s flat and realises that Kalpana and Arivu were already aware. Kannan reveals to Rukku that Rajadurai was on duty on the day of the bank heist and reveals privately to Rukku what Rajadurai told him.
Kannan devises an ingenious plan to trap Dharma and Rajadurai. He tells Kalpana to seduce Rajadurai at the pub, and also tells Rukku to go to the police and report Rajadurai for domestic abuse. At Rajadurai's house, Kannan fights and kills Dharma and his goons. Eventually, Rajadurai comes home to find the stolen money and dead bodies. Kannan incapacitates him and leaves with the RM 1,000,000, leaving behind half of the stolen money. Meanwhile, Kalpana places the rest of the stolen money in Dharma’s vehicle. Rukku enters her house to find Rajadurai, plays a gunshot sound on her phone, making it seem like Rajadurai has fired at her. The police promptly arrive and shoot Rajadurai dead. Preethi is relieved upon seeing news of Rajadurai’s demise. The police conclude their investigation and reveal to the media that there was a scuffle between Dharma and Rajadurai, leading to their deaths, and that all of the stolen money was recovered from their possessions.
Kannan, Arivu, Rukku and Kalpana are shown to have escaped successfully, celebrating with the lottery winnings. Meanwhile, Arivu is informed that the real "Bolt" Kannan never arrived in Malaysia, thus realising that he has befriended a fraudster. When he asks “Kannan” for his real identity, he simply smiles as the credits roll.
