An elderly Malaysian man goes ballistic and kills several Indian officers in a span of 5 minutes at the Indian Embassy in Kuala Lumpur, Malaysia, before collapsing. A tattoo of a love symbol is present at the back of his neck, leading RAW officials to conclude that it is the handiwork of a criminal scientist named Love, whose identity and whereabouts are unknown to anyone except Akhilan Vinod (Vikram), a suspended RAW agent whose wife Meera George (Nayantara), a leading computer analyst at RAW, was killed by Love 4 years ago. RAW chief Malik (Nassar) tracks down Akhilan and convinces him to join the investigation. On viewing the video footage of the attack, Akhilan comes to the conclusion that the elderly Malaysian man had taken a mysterious performance-enhancing drug which allowed him to attack the Indian officials and decides to investigate the matter further in Malaysia. Since Akhilan is under suspension, Malik assigns him as a deputy to a junior RAW agent Aayushi (Nithya Menen), who is officially assigned to handle the case, and the two of them leave for Kuala Lumpur.

It’s the story of two childhood friends and their escalating competitive nature. To what extent are they ready to go?

Arjun Krishna (Vikram Prabhu), a technician in a Chennai-based BMW showroom, meets Anamika Raghunath (Priya Anand), a college student, while out with her friends at Hard Rock Cafe. They are attracted to each other and go on a date the following night. Following the date, Anamika invites Arjun to her apartment for a bottle of vodka. Things go well until Anamika gets kidnapped by two men. Arjun, who was in the bathroom when Anamika was kidnapped, immediately lodges a complaint at the Besant Nagar police station. Sub-Inspector Arumugam (M. S. Baskar), who is assigned the case, then goes to Anamika’s apartment along with Arjun, but finds that the apartment is cleaned up and there seems to be no sign that a kidnapping has taken place, while the apartment’s watchman insists that Anamika had not returned to her apartment for three days. Also, the CCTV camera installed at the apartment does not show any men arriving and taking away Anamika, prompting Arumugam to suspect that Arjun has lodged a false complaint as he is drunk. However, when Arumugam calls up Anamika’s father Raghunath Kumar (Shankar Sundaram), the chairman of the TV news channel Channel 24, he merely replies that he doesn’t know anything about the kidnapping and that Anamika is holidaying in Goa, at which Arumugam suspects something amiss, realising that Arjun had not lied after all. Arumugam and Arjun rush to Raghunath’s mansion, where they see him being threatened by the two men who had kidnapped Anamika as well as the police inspector of Besant Nagar to give them a SD card which has some critical information. Raghunath calls up his editor and asks him to give the SD card to the three men, after which he is killed by them. Arjun and Arumugam pursue the three men. While Arjun manages to kill the police inspector, the other two men escape, killing Arumugam in the process.
