On the eve of the third Indo-Pakistani war in 1971, the situation between the two sides was tense and imminent. At this time, a Kashmiri businessman who had close contact with the Pakistani military and was actually an Indian spy found out that he had lung cancer and was running out of time. He made a difficult decision to let his daughter Samat (Alia Bhatt), who was in the prime of his life, marry the enemy country to complete his unfinished mission. So, Samat stopped her studies, and after a short training, she became the newlywed wife of Iqbal (Vicky Kausar), the youngest son of a lieutenant general of the Pakistani army, and became an Indian spy with an important mission. Time is running out. Facing a brand new environment and a family that is both friendly and vigilant, Samat must race against time to obtain top-secret war intelligence. However, the cruel nature of war still far exceeds Samat's expectations.
