Forensic officer Mugilan falls in love with Megha. But she disappears around the same time as when Mugilan discovers incriminating evidence against a corrupt police officer who is up for a promotion.
An injured Mugil (Ashwin) collapses in front of Angana Roy who happens to be his fiancée as well as a nurse working at a hospital. After recovering, Mugil starts narrating his own brewing love story with Megha (Srushti). The movie switches back and forth where the romance portions are narrated in the flashback and an intriguing series of sequences happen at the hospital.—Ravichandran
