The car in which Surya, his parents and best friend Vignesh are travelling is hit by a lorry. His parents die on the spot while Vignesh survives and an unconscious Surya is admitted to the hospital. After coming to a few days later, he fails to recognise the faces of his deceased parents and Vignesh, leading to his doctor to diagnose him with phonagnosia and prosopagnosia, also known as "face blindness".

A few years later, Surya witnesses a murder and anonymously reports it to the police. However, he is unable to identify the murderer due to his incurable conditions. Whether he helps bring the justice to the victim forms the rest of the story.
