Set in the beautiful Kullu valley of Himachal Pradesh, Saanjh follows the journey of Sanju, a 16-year-old city girl who becomes the victim of bogus social-media posts. When her father discovers a compromising online video in which Sanju supposedly features, he consigns her to their remote ancestral village to stay with her grandmother. Isolated and dejected, Sanju encounters ill-mannered house guest Jonga and finds surprising solace in his company. Unable to adjust to the village lifestyle, she hatches a plan to escape the village with help of Jonga, but need time to raise enough cash. Meanwhile, Sanju slowly begins to understand her grandmother’s pain—living a secluded life with almost no contact with her children—and a deep bond grows between them. When the grandmother falls sick, the film focuses on one unforgettable Saanjh (evening) in which they are caught between light and darkness.
