Moonar starring by Ranjith, Rithi. ‘All the incidents in this film are fictitious……. Until they happen to you’. We see an upanishad quote about death. The film begins with Chakravarthi shouting in anguish inside a dark forest.
The film cuts to Arya, and the introduction song. We learn that Karthick (Arya) is an architect. He meets Sandhya (Trisha) in a go-carting race, and falls in love as soon as he sees her. Sandhya is a doctor, and so Karthick goes to her hospital and tries to woo her. Sandhya hates Karthick as she thinks he is not serious about life. Gradually, she falls for him, and the two happily enjoy life.
We also see Eashwar, a man who has lost his wife and son in a road accident. Eashwar thinks that it was Naushad – the man who accidentally hit Eashwar’s wife (Anu Hassan in a cameo) and son with his car – who is solely responsible for their death, and he repeatedly stalks Naushad and threatens him that he doesn’t understand the loss Eashwar has undergone and he will only understand it if his own son dies. Naushad has a little boy Iman, and Naushad finally hides in Munnar, fearing Eashwar.
It is at this point that the story takes a serious turn. Sandhya dies in a brutal accident, and Karthick is devastated. Sandhya’s father tells Karthick that Sandhya’s heart has been transplanted and it’s Naushad’s son who is living with her heart. Karthick becomes emotional and goes on a trip to find out Naushad. By following Karthick, Eashwar too arrives at Munnar. What happens at Munnar forms the rest of the story. Was Eashwar successful in his mission to kill Naushad’s son? Was Karthick able to overcome his grief? See the movie.
