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.
