Durga (Nayanthara) has to forgo active duty as a CBI officer after a car accident leaves her visually impaired. However, what she does not forgo is her sense of duty and ability to adapt her handicap with her training, which helps her pursue a ruthless sociopath whom she has a run-in with. Aiding her on her quest are SI Manikandan (Manikandan R. Achari) and food-delivery boy Gautham (Sharan Shakti).
