Revolving around undertrial prisoners who languish in jails while awaiting a judgement, the movie follows Surya Prakash who gets caught in a similar situation while being on trial for the murder of a powerful man.

The film opens with Pavalakkodi (Nayanthara) in the hospital and her father Vairakannu (Thambi Ramaiah) weeping for her misfortune. Later, the scene cuts to their futures.
They live in a small house. Vairakannu is a single hardworking father who brought her up and Pavalakkodi, his only daughter, takes care of him in his old age and doesn’t wish to marry. They lead a happy life. Nearby in an apartment, three thieves enter a house and rob all the jewels from the lady, harass and kill her. To investigate this case a Police officer (Harish Uthaman) arrives at the site and finds no clue about the men and finds a Rajasthani blanket in the house. Upon asking, the house owner and maids say nothing, and therefore the case leads to nothing.
