Plot
In Pondicherry, rifle‑club owner Prabhakar purchases land worth ₹20,000,000 (equivalent to ₹60 millionorUS$710,000 in 2023), discovers he's been swindled by Jayabal, and commits suicide. The notorious gangster Dracula Pandiyan's son, Dracula Bobby, murders Narasimha Reddy, beheads him, and sends the head to his brother Reddy; Reddy vows revenge. Eighteen years later, Prabhakar's second daughter, Rita, works at a fried‑chicken restaurant and is preparing for her niece Yazhini's birthday. Still seeking vengeance, Reddy hires an assassin named Martin "Master" to kill Pandiyan for ₹5 crore. Master lures Pandiyan through a pimp, Lallu, claiming a call‑girl named Sonia is waiting. Drunken Pandiyan mistakenly enters Rita's house; Rita and her mother, Chellamma, demand he leave, but he draws a gun, and Chellamma strikes him with a pressure‑cooker lid, causing him to collapse and die.
Rita presses on with Yazhini’s birthday party, so no one suspects anything. While Pandiyan's phone call with Lallu is still live, Master and his crew learn of Pandiyan's death and plot to steal the body that night after the party. Rita's elder sister Riya identifies the corpse as gangster Dracula Pandiyan and mentions his son, Dracula Bobby. Chellamma urges surrender, but Rita refuses, recalling her past clash with Inspector Kamaraj—who was suspended after she posted a video of him demanding free chicken soup—and vows not to hand herself over. Rita hides Pandiyan's body in the fridge and schemes to buy a used car as dowry for her brother‑in‑law, Gowri Shankar "Gowri," who is currently separated from Riya. She plans to drive the car under the pretence of taking Reena to her NEET exam at Pondicherry University through the Auroville forest, dump the corpse in a trolley suitcase, give the car to Gowri, and thereby reunite Riya with her husband.
When Master learns of this plan, he decides to seize Pandiyan's corpse that very night. Lallu demands his ₹50 lakh fee immediately, so Master and Doss lure him to the Old Harbour to kill him. Meanwhile, Kumar and Babu are watching Rita's house. Doss knows Master is set to receive ₹5 crore from Reddy but will only share ₹10 lakh with them, so Doss, Kumar and Babu join forces and murder Master and inform Reddy. Lallu, having witnessed the three kill Master, panics and falsely claims he has already left for Hyderabad. At a bar, Doss, Kumar and Babu are arrested by Kamaraj. Gowri arrives to see his one‑year‑old daughter, Yazhini. Chellamma accidentally blurts out that they killed Pandiyan. Riya suggests they get Gowri heavily drunk so that he will forget the night's events, and so they load him into an auto and drop him at the police station. The next morning, Bobby is furious that his father is missing and asks Kamaraj to help find him, also searching for the pimp Lallu, who had lured Pandiyan.
Doss, Kumar and Babu break out of the police station and ask Reddy to meet them at the Old Harbour that afternoon to collect Pandiyan's head. Rita purchases a used black Honda City – the same car Pandiyan had left his house in the night before; it was stolen and sold to her that morning. With Kamaraj's help, Bobby tracks his father's mobile, and a car‑thief tip leads Kamaraj to discover that Rita now owns the car, giving him a chance to settle his earlier grudge against her. Rita and her family pack Pandiyan's corpse into a trolley suitcase and hide it in the boot of their car. While driving to Pondicherry University to drop Reena, they are bumped at a petrol station by Pandiyan's dim‑witted second son, Cheetta, which causes the boot to get locked. Chellamma breaks the trunk‑release lever, and after a hurried stop at a mechanic who wires the door shut, they continue.
At the university, Doss and his two henchmen are waiting to ambush Rita, while Bobby tracks down the pimp Lallu and Kamaraj obtains Rita's address; both groups learn the family is at the exam venue. Meanwhile, Reddy arrives at the Old Harbour demanding Pandiyan's head. Bobby, frustrated by the delay, assaults a travel vlogger on the road, and Cheetta suggests they look for the call‑girl Sonia instead of Lallu. Gowri climbs into the car, and the family labels him a lunatic and dumps him at a mental hospital. Sonia's reels later reveal her identity to Bobby. Doss spots Rita, but Kamaraj intervenes, framing Rita for stealing Pandiyan's car and demanding a ₹50‑lakh bribe or sexual favours. Rita angrily refuses. Doss attempts to retrieve the corpse from the car trunk while it sits in the police station. But Rita uses the mosquito‑smoke being sprayed to distract Kamaraj, steals the car key, and escapes. Doss and his sidekicks break into the station, fight the officers, and escape to pursue Rita's car. Through Lallu, Bobby learns that Pandiyan had last entered Rita's house.
When Doss confronts Rita and demands Pandiyan's corpse, the trolley case is gone. It is revealed that Sonia and Lallu had trailed Rita, and while Rita's family was at the mental hospital, they moved the corpse into their car to claim the ₹5 crore ransom from Reddy. Doss forces Rita to reveal Lallu's location, intercepts Lallu and recovers the corpse, and murders both Sonia and Lallu. He then tells Reddy he now holds the body. To eliminate potential witnesses, Doss orders Kumar to shoot Rita, but Babu shoots Kumar instead. While captive, Rita convinced Babu to kill Doss and Kumar so they could split the ransom. Believing Rita, Babu kills Doss, but Rita knocks Babu and escapes with her family. She contacts Kamaraj, offering ₹5 crore instead of the earlier ₹50 lakh bribe and hands over Pandiyan's corpse, falsely claiming that Doss and his gang killed Pandiyan and that she fled the police station after they tried to escape with the body.
Kamaraj finalises a deal with Reddy. Rita, fearing the corrupt Kamaraj, sends her location to Reena and arranges for Bobby—who is hunting them—to meet her through Reena. When Bobby arrives, he threatens both Kamaraj and Rita to reveal the truth about his father's death. Rita, speaking boldly, accuses Kamaraj of framing her family for the murder and wins Bobby's trust; he then kills Kamaraj. As Rita and her family prepare to leave, Cheetta appears, having found Pandiyan's chain in the kitchen and suspecting Rita. Riya confesses that Rita and Chellamma killed Pandiyan. Before Bobby can shoot Rita, Reddy arrives, erupting a gunfight between Bobby's gang and Reddy's men. Rita knocks Bobby down and hands a pistol to Reddy, and Reddy shoots Bobby dead. Reddy thanks Rita and turns to leave, but Rita draws gun on him, revealing that Reddy's full name is Jayabal Reddy, the one who swindled Rita's father, Prabhakar, out of a ₹2 crore land deal 18 years earlier, driving Prabhakar to suicide.
Rita explains that she saw Jayabal Reddy's photo with Doss and decided to seek revenge. So she manipulated Babu into killing Kumar and Doss, and steered Bobby into killing Kamaraj and Reddy against Bobby, clearing the way for her revenge. She then shoots Reddy and leaves with the ₹5 crore ransom money. Cheetta, thanks Rita and declares that with Pandiyan gone, he will claim the vacant donship of Puducherry.
