The film opens with a fight between two individuals on a rainy night in a deep, dark forest. In the opening scene, a title card is presented with an Upanishad quote: "Death is just the beginning of another life".
Karthik is a carefree architect who comes across Sandhya, a pediatrician, in a go-kart race. Karthik immediately falls in love with Sandhya and wants to convince her to marry him. Karthik finds out several facts about Sandhya and arranges a meeting by pretending that she caused a car accident and damaged his car. When that approach fails, he goes to the hospital where Sandhya works, becoming a regular visitor and making efforts to woo her. Sandhya, however, has other interests and shows no signs of reciprocating his love. She believes that Karthik is too carefree and not serious about life. One day, Sandhya's parents tell her about her to-be-fixed marriage. She finally recognizes that Karthik is the right match and slowly develops a deep love for him. She wholeheartedly agrees with the marriage.
Simultaneously, a morose, mysterious man, Eashwar, who always moves around with his Rottweiler, goes to see Naushad, a software engineer who happily lives with his eight-year-old son Imaan. A few months ago, Naushad had accidentally hit and killed Eashwar's wife Geetha and son Naveen in a car crash. Eashwar, apparently mentally disturbed, keeps murmuring that Naushad was solely responsible for their deaths. Eashwar keeps following Naushad, telling him that he will feel the same pain only when his own son dies. A workmate of Naushad informs him that Eashwar had visited him and requested information about Naushad, and tells him to be aware. He and his son escape to his friend's place near Elliot's Beach, Chennai.
Meanwhile, Karthik and Sandhya, who happily spend time together, are ready for marriage and make plans for the future. Karthik then suddenly asks Sandhya to postpone their marriage for a year. However, Sandhya insists on marrying at the earliest possible date. To solve this problem, they decide to hold a cycling race across a road on Elliot's Beach so that the winner makes the decision, which the loser must accept. At the same time, Imaan and his friend fly a kite on the terrace of Naushad's friend. Suddenly, Imaan faints and falls, which distracts the boys, and they let the kite fly away. Sandhya, who is ahead of Karthik and leading the race, rides straight into the kite thread, which cuts her neck, fatally injuring her. She dies in the hospital from blood loss.
Six months later, Sandhya's father visits Karthik, who is under depression following her death, and informs him that even after death, Sandhya has saved the life of a child, since her heart has been transplanted into a boy, who happens to be Imaan. Karthik becomes emotional and overjoyed that at least one part of his love is alive, and goes to meet Naushad and Imaan. He finds out that they have left their home in Chennai and moved to Munnar in Kerala. He travels to Munnar to see them and feels happy again, while learning from a grateful Naushad that Imaan suffered from cardiomyopathy and Sandhya's heart had saved his life. Meanwhile, Eashwar, who had followed Karthik, also arrives in Munnar, where he meets a car mechanic Syed (who used to play professional football with Eashwar), and allows Eashwar to stay at his home.
Karthik goes to see the father and son one last time before returning to Chennai, when suddenly, a car hits Imaan. Karthik, who was just ready to go home, comes back and saves Imaan. Shocked by that incident, Karthik does not believe that it was merely an accident and wants the truth from Naushad, who has been admitted to the hospital after having been injured in the accident. Karthik then learns about Eashwar, who was the man in the car, and his intentions. Eashwar has bought the same car that killed his family and seeks revenge for their death by killing Imaan in return. Karthik decides to take Imaan to a nearby place where he had stayed before, promising Naushad that he will protect and look after Imaan.
Subsequently, Karthik tries to befriend Imaan, who dislikes him and wants to stay with his father. When they later travel by car, Karthik and Eashwar encounter each other, and Eashwar threatens Karthik. A cat-and-mouse chase follows, where Eashwar wants to dispose of Karthik to get to Imaan and kill him. Syed sees Eashwar chasing Karthik and offers to help after hiring some local goons, who will kill both silently without mentioning Eashwar's and Syed's names. One night, after mixing snake venom in their knife, the goons reach Imaan's house, scratch Karthik's waist with that knife, and Karthik slightly faints due to the snake poison; however, he summons his strength, fights the goons back, and protects Imaan.
However, Eashwar finds the still-alive Karthik and Imman in the heart of the forest. A fight ensues, with Eashwar initially gaining the upper hand and beating Karthik, who becomes unconscious due to the snake venom and falls into a grave, which Eashwar then fills after to kill him, and hunts Imaan down in a derelict church. However, Karthik reemerges from the grave and attacks Eashwar, overpowering him and breaking his arm and leg, paralyzing him for life, albeit sparing him alive.
A now-paralyzed Eashwar is admitted to the hospital and treated for his condition. Karthik escorts Imaan and Naushad back to Chennai from Munnar and makes them stay with him in his new house, which he had constructed for Sandhya.
