A woman from a village in Tamil Nadu marries a sophisticated city dweller and moves with him to Kashmir, where all is rosy - until he gets kidnapped by militants.
Roja, a young woman born and brought up in Southern India, prays that the handsome young man coming to see her sister will be her future brother-in-law, only to have the tables turned on her when he openly choses her over her sister (as her sister loves another). So Roja marries Rishi and they leave the village to settle in the city, where both fall in love. Rishi, who works for the Indian Government, is instructed to go to the troubled state of Kashmir on a classified mission. Roja also goes along. Then her innocent world is shattered when Rishi is abducted and held for ransom by a group of jihadist militants who want an independent Kashmir and the release of a terrorist held by the Indian military forces. Will the passionate appeal of this young woman move cold and ruthless military and politician's hearts and minds? Two of the songs are worth remembering after watching the Hindi-dubbed version of the movie: "Dil hai chhotasa, chhotisi aasha, masti bhare man ki bholisi aasha, chand taroh koh choone ki aasha, aasmano me udhne ki aasha..." and the unforgetably hilarious and popular "Rukmani, Rukmani shaadi ke baad kya kya hua, kaun haara kaun jeeta, khidki mein se dekho jara...."
- In Srinagar, a Kashmiri terrorist, Wasim Khan, is captured by a team led by Colonel Rayappa. In South India, 18-year old Roja is a simple village girl born and brought up in Sundarapandiapuram in Tirunelveli district in southern Tamil Nadu. Roja fervently wishes that her sister Shenbagam's marriage proposal with Rishi Kumar, a cryptologist working with the R.A.W. of India, goes smoothly. Unknown to her and her family, Shenbagam is in love with the son of her paternal aunt.
When Rishi wishes to speak to Shenbagam alone, she gathers enough courage to convey this and politely asks him to reject her in front of her parents, to which he obliges. To everyone's surprise Rishi requests Roja's hand in marriage instead. Being unaware of Shenbagam's love affair, Roja is not willing to accept Rishi's proposal as she believes that he is the best match for Shenbagam but she marries Rishi, and the couple go to live in Madras while Shenbagam marries her cousin.
Initially Roja does not like what Rishi did, but when she learns of Shenbagam's love affair and consequent rejection of Rishi, she apologizes and starts seeing him in a new light. Love blossoms, and life is blissful for the couple for a short while. Meanwhile, due to the illness of his Chief, Rishi is assigned to an army communications centre in Baramulla to intercept military intelligence. The couple find themselves in a beautiful yet alien land. Roja's world turns upside down when Rishi is abducted by terrorists whose agenda is to separate Kashmir from India and free their leader, Wasim Khan, from judicial custody.
Faced with the daunting task of rescuing her husband, Roja runs from pillar to post, pleading with politicians and the military for help. Further complicating matters is the communication gap: She can't speak their language, and they can't speak hers. Meanwhile, Rishi, held captive by a group of terrorists led by Liaqat, an associate to Wasim Khan, tries to reason with the terrorists, about their misdirected motive for the liberation of Kashmir. Liaqat's sister shows a little compassion towards him. Initially, when Roja's efforts fail, the Indian government denies any negotiations with the terrorists for the release of Rishi in the media.
The angered terrorists attempt to burn an Indian flag. Rishi risks his life to put out the fire and shows the terrorist how much the country means to him, a regular citizen. When Liaqat's younger brother, who with a few other youths from his village was sent across the border to Pakistan for training, is shot by the Pakistan Army, Liaqat's strong belief is shaken, but he still manages to convince himself of the cause. Consequently, Roja's efforts to apprise the politicians of her suffering and pain are successful as a minister pities her and offers to help.
Much to the chagrin of Rayappa, the government decides to release Wasim Khan in exchange for Rishi. Rishi, not wanting to be used as a pawn to release a dangerous terrorist, gets help from the sympathetic Liaqat's sister and escapes - with Liaqat and his men chasing him. Rayappa, Roja and other army officers get to the hostage exchange spot with Wasim Khan, but Liaqat does not show up. The Army locks Wasim Khan up in the prison.
Rishi has managed to get close to the exchange spot on his own after evading the terrorists. During his escape, Rishi kills two terrorists. Liaqat catches up with him and holds him at gun point. Rishi reasons with Liaqat further and convinces him that his war is immoral. Liaqat lets Rishi go and he goes to the exchange spot. Liaqat escapes from the Indian Army. Rishi and Roja are united once again.
