95-year-old Ishar Singh Grewal (Shah) suffers a stroke and is on his deathbed. Despite failing health and advanced dementia, he refuses to let go of life, desperately muttering about returning to his ancestral home in Sargodha, Pakistan. His grandson, Nirvair (Dosanjh), acts as his caregiver and attempts to make sense of his disjointed ramblings.
The story goes back 78 years to undivided India. A younger Ishar (played by Vedang Raina) falls passionately in love with a woman named Jia/Afsana (Sharvari). Their budding romance is abruptly shattered by the violence and mass migration of the 1947 partition of India, forcing them apart.
Nirvair investigates his grandfather’s past to give him peace, eventually locating Afsana’s family. He discovers a devastating truth: Afsana died 10 years prior, having spent her life waiting for Ishar to fulfill his promise to return. Through a video call, Ishar hallucinates a vision of a young Jia and finally asks her for "permission to leave." She grants it, allowing him to pass away peacefully.
