In the middle of the night, Indhiran, accompanied by his friends Sathish and Karuna, buys a gun illegally from a local gangster. Back home, Indhiran stares at his wish list and recalls his past.
Past: Since childhood, Indhiran has narcolepsy, a rare disorder that makes him fall asleep whenever his emotions reach an extreme level, preventing him from living a normal life. He needs to be escorted at all times, despite excelling in academics, and he cannot impregnate women because he falls asleep during sex, though he can still hear everything said while he sleeps. To cope, he builds a bucket list of goals he wants to achieve on his own. One day, he ventures out alone, ticking off a goal, but when a vehicle nearly hits him while crossing the road, fear triggers a sudden sleep.
A passerby makes him pose as an orphaned corpse and gathers money from onlookers for his burial. Meera, who passes by, takes pity and shells out almost five thousand rupees. Later, Meera meets Indhiran in a shopping mall and faints from shock upon seeing him alive. After clearing the misunderstanding, they start dating and fall for each other. Meera makes one of Indhiran’s dreams come true by kissing him, but her father Jayaprakash opposes their marriage as Indhiran cannot stay awake during sex. Meera urges Indhiran to find a way to stay awake. It dawns on Indhiran that he had never fallen asleep while taking a shower. Believing that her father will accept Indhiran only when his sexual potency is proved, Meera and Indhiran have sex in his swimming pool, resulting in Meera becoming pregnant.
On a late-night drive, Meera drives her car on an under-construction bridge. Meera’s car is hit by another, and the shock makes Indhiran doze off while Meera is attacked and raped by unknown thugs. Indhiran can hear the entire ordeal but remains asleep, and he sheds a tear for being helpless. Meera falls into a coma, and her child is aborted. A heartbroken Indhiran vows to exact revenge on the perpetrators.
Present: Deciding to exact vengeance all by himself, Indhiran fails to testify to the police. He begins to question people who knew Meera. Inquiring Meera’s friends, Indhiran first suspects Karthik, a rich but ill-mannered guy whose marriage proposal was rejected by Meera. Indhiran confronts him, but he denies any knowledge about the incident, even offering to help Indhiran if required. Indhiran realises that the sound of sudden obstacles makes him sleep. To prevent this, he buys a portable audio player and uses it with full volume. A transformer explosion right next to him has no effect on him because of the music, and thus he realises his newfound advantage.
Indhiran also reaches out to a meditation teacher who teaches him about staying calm and being immune to shock by anticipating the event in advance. He stays awake a full night and tries to control his sleep by standing between two loud trains with the audio player playing at full volume. After obtaining control, Indhiran gets information from a sympathetic police officer regarding attack cases to find a lead. He remembers one of the thugs’ name Sekhar and his ringtone, while the police find out that the criminals drove a red car. Indhiran stumbles upon a red car at a petrol bunk and inquires the driver, who claims that the car was with a mechanic named Sekhar on the day the crime took place.
At the workshop, Indhiran spots the mechanic who tries to run upon recognizing Indhiran, and a chase ensues, leading them to a building under construction. Informed by [Sathish], Karuna arrives there and kills Sekhar. He then injures himself to convince Indhiran that he was assaulted by Sekhar who escaped the scene. He is then admitted for treatment.
Past: Married to Karuna for two years, Kavitha was dissatisfied with her drunkard husband; she begins an affair with Aravind, a wealthy friend of Karuna. He spends a lot of money buying her expensive gifts. Indhiran gains knowledge of this and advises Kavitha against it. It turns out that Karuna, to realise his ambitions of running a business in the US, had been using his wife to manipulate Aravind. Citing Indhiran’s confrontation, Kavitha lied to Aravind that if Karuna learns of their affair, he would kill them both. She suggested that the only way to solve it once and for all is to arrange ₹ 20 million that Karuna needs to settle in the US. With him gone, they could enjoy being together. Aravind agreed to finance Karuna out of his lust for her.
Later, when Karuna and Kavitha are celebrating their success, Indhiran drops by unexpectedly. Indhiran suspects them and informs Aravind, who confronts the couple. When Aravind realises that he had been cheated, he hits Kavitha in a fit of rage, and she dies after the hit lands her head on the corner of a cupboard. Infuriated, Karuna retaliates and kills Aravind. Karuna arranges for disposing of the two bodies with the help of the thugs and lies to Indhiran that Kavitha has eloped with Aravind. Since he assumed that Indhiran was responsible for Kavitha’s death, Karuna had planned to take vengeance by making him suffer the same way and requested the thugs to attack Meera.
Present: The remaining thugs insist Karuna to bring Indhiran to the same place where Sekhar was killed. Finding out that it was Karuna who had killed Sekhar, they beat him up. When Indhiran arrives, the thugs remove the audio player from Indhiran, who gets an adrenaline rush and dozes off. While the thugs are thrashing him, one of them breaks a water pump, which splashes water all over and awakens Indhiran, who kills them all, except Karuna. Indhiran says that he had seen Karuna killing Sekhar. When Indhiran questions Karuna as to why he sent thugs to attack Meera, Karuna angrily tells him that it was revenge for Kavitha’s death, which was caused by Indhiran telling Aravind the truth.
Karuna angrily attacks Indhiran and Indhiran retaliates by hitting Karuna violently. Despite feeling bad for his friend and hesitant to kill him due to their close friendship, he remembers Meera and kills Karuna by kicking him into a steel bar. With all his wishes fulfilled, Indhiran has a new wish that he would help Meera recover soon. The final scene shows Indhiran hugging Meera, who is tearful hearing him, which shows that she is definitely recovering.

Why does Indhiran fall asleep during the attack on Meera?
Indhiran suffers from narcolepsy, a rare disorder that causes him to fall asleep whenever his emotions reach an extreme level. When Meera's car is hit by another vehicle on the under-construction bridge, the shock triggers his condition. While asleep, he can still hear everything happening around him, which is why he hears the entire assault but cannot physically respond. He only manages to shed a tear, helpless to save Meera.
Earlier in the film, Indhiran nearly gets hit by a vehicle and fear immediately triggers a sudden sleep episode.
How does Indhiran learn to control his narcolepsy?
Indhiran discovers that loud sudden sounds trigger his sleep, so he buys a portable audio player to block out external sounds. A transformer explosion has no effect on him because of the music playing at full volume. He also consults a meditation teacher who teaches him to stay calm and anticipate shocks in advance. He practices standing between loud trains with music playing and eventually gains enough control to stay awake through his revenge mission.
Indhiran realizes he had never fallen asleep while taking a shower, showing his condition can be managed in certain states.
Why did Karuna order the attack on Meera?
Karuna orchestrated the attack on Meera as revenge for his wife Kavitha's death. When Indhiran discovered Kavitha's affair with Aravind and told Aravind the truth, it triggered a chain of events that led to Kavitha's accidental death and Aravind's murder by Karuna. Believing Indhiran was responsible for Kavitha's death, Karuna wanted him to suffer the same way by having his loved one attacked.
The timeline shows Karuna and Kavitha celebrating their success after manipulating Aravind, just before Indhiran drops by unexpectedly.
What is the connection between Kavitha's death and the attack on Meera?
The attack on Meera was directly caused by the events surrounding Kavitha's death. Karuna used his wife to manipulate Aravind into funding his US immigration plans. When Indhiran exposed the affair to Aravind, Aravind confronted Kavitha and accidentally killed her during a physical altercation. Karuna then killed Aravind and arranged for the bodies to be disposed of by thugs. Karuna blamed Indhiran for this chain of events and arranged the brutal attack on Meera as retaliation.
Indhiran advises Kavitha against the affair, not knowing this conversation will lead to his own tragedy.
Why does Sathish kill Sekhar at the construction site?
Sathish kills Sekhar to prevent him from revealing the truth about who hired the thugs. When Indhiran tracks the red car to a workshop and confronts Sekhar, the mechanic tries to flee. Sathish arrives at the scene and kills Sekhar, then injures himself to make Indhiran believe Sekhar attacked him and escaped. This cover-up protects Karuna, who had ordered the attack on Meera.
The timeline establishes that Sathish and Karuna are Indhiran's friends who accompanied him to buy the gun, creating opportunity for this betrayal.
Does Meera recover from her injuries in the end?
The final scene shows Indhiran hugging Meera, who is tearful while hearing him, indicating she is recovering from her coma. After completing his revenge, Indhiran's new wish is to help Meera recover soon. While the movie does not show a complete recovery, the ending suggests hope that she will heal with his support.
The entire revenge plot is driven by Indhiran's vow to get justice for Meera and help her recover.
Why does Karuna kill Aravind?
Karuna kills Aravind after Aravind discovers he has been manipulated. Kavitha had convinced Aravind to finance Karuna's US immigration by promising they could be together once Karuna left. When Aravind confronts the couple and realizes he has been cheated out of money, he strikes Kavitha in rage, causing her to die when her head hits a cupboard corner. In retaliation, Karuna kills Aravind and arranges for the thugs to dispose of both bodies.
Karuna was using his wife to manipulate Aravind for his business ambitions from the start.
How does Indhiran find the attackers responsible for assaulting Meera?
Indhiran uses his newfound control over narcolepsy to investigate systematically. A sympathetic police officer provides him with information about attack cases. Indhiran recalls one of the thugs' name (Sekhar) and his ringtone. The police also discover the criminals drove a red car. Indhiran traces the red car to a petrol bunk, where the driver reveals it was with a mechanic named Sekhar. Following this lead takes him to the workshop where the confrontation occurs.
Indhiran remembers the ringtone of one of the attackers while the police find the red car clue.
Why do the remaining thugs beat up Karuna at the construction site?
The thugs beat Karuna because they discover he was the one who killed Sekhar. Earlier, Karuna had asked the thugs to bring Indhiran to the same location where Sekhar was killed. The thugs realize Karuna set them up and killed their associate, so they attack him. Later, when Indhiran removes Karuna's audio player and he gets an adrenaline rush, he falls asleep, allowing the thugs to attack him until a water pump wakes him.
The thugs had helped Karuna dispose of bodies earlier, creating a dangerous alliance built on mutual secrets.
What happens to Meera's pregnancy after the attack?
Meera becomes pregnant after she and Indhiran have sex in his swimming pool, fulfilling one of his dreams. However, after the brutal attack on the under-construction bridge, Meera falls into a coma and the child is aborted as a result of the assault. This loss adds to Indhiran's determination to seek revenge for what was done to Meera.
Meera urgers Indhiran to find a way to stay awake so her father would accept him, leading to the pool scene.
Why does Indhiran kill Karuna despite their friendship?
Indhiran kills Karuna after learning the truth behind Meera's attack. Although they were close friends, Karuna had orchestrated the assault on Meera as revenge for Kavitha's death, which he blamed on Indhiran. During their confrontation, Karuna attacks Indhiran violently. Despite feeling bad for his friend and hesitating due to their close bond, Indhiran remembers Meera's suffering and kills Karuna by kicking him into a steel bar, ending the friendship forever.
Karuna had planned to make Indhiran suffer the same way he did by having Meera attacked.
Why does Meera's father oppose their marriage?
Meera's father Jayaprakash opposes the marriage because of Indhiran's narcolepsy condition, specifically his inability to stay awake during sex. He believes Indhiran cannot fulfill his duties as a husband. Meera encourages Indhiran to find a way to overcome his condition, leading to their discovery that he can stay awake during a shower and their subsequent intimate encounter in the swimming pool.
This opposition drives the plot forward as Meera and Indhiran seek ways to prove his capability.
