The movie Naina starts from the city of London. During a solar eclipse, a young girl called Naina is involved in a tragic road accident. Unfortunetely both her parents are killed and Naina loses her eyesight too. Twenty years later and Naina (Urmila Matondkar) receives a state-of-the-art cornea impant, which restores her vision.
However there’s a terrible twist in store for Naina. She starts visualising supernatural things, which are invisable to everyone else. Soon she begins a quest to understand her bizarre new ability… a quest that leads to the unexplainable slowly being explained.
