Chandar Prakash (Rishi Kapoor), who lives in Srinagar, is due to be engaged and married to Chandni Kaul (Ashwini Bhave), whom he calls Chand. On the day of the engagement, he experiences an accident, and mistakenly strays into the Pakistani side of Kashmir. A native girl, Henna (Zeba Bakhtiar), falls in love with him; this is amidst the India-Pakistan tensions in Kashmir, which leads to him being suspected, by the Pakistani police, of being an Indian spy.
Beautiful Henna Khan lives a transient life near the river Jhelum, in Pakistan, with her widowed dad, Khan Baba, and three brothers Ashraf, Razzak and Zaman. One day, she comes across an unconscious man who has washed ashore. Khan Baba, Gul Bibi (the village doctor) and Henna take this stranger in and nurse him back to health, only to find out that he has lost his memory. The man, in his sleep, cries out the name "Chand!", thus everyone starts calling him by that name. Soon, he is well enough to walk around and starts working for Gul Bibi, helping her make clay pots. Henna falls in love and wishes to marry him, much to the chagrin of Daroga Shahbaaz Khan (Raza Murad), who has already been married twice; according to Shariat law, he can marry twice more. Khan Baba arranges the marriage of Henna and Chand; a day is set for the marriage. On the day of the wedding, Chand finally regains his memory. The family finds out that “Chand” is actually Chandar, and he is neither a Muslim nor Pakistani. He is from India, having strayed across the border into Pakistan after a random car accident. The group decides to ensure a safe passage for Chand to get back home.
The first attempt is foiled, due to one of Henna’s brothers colluding with Shahbaaz Khan. The second attempt succeeds, but Henna ultimately loses her life in the chaos.
The film ends with Chandar asking why war must be.
The film was a hit, especially given the locations it was shot in, and for the excellent musical score by Ravindra Jain, which spawned internationally-known hits such as "Main Hoon Khush Rang (I’m Happy)", "Anaaradana (Pomegranate)" and "Der Na Ho Jaaye Kahin (Don’t Be Late)”.
