In the rain-slicked, labyrinthine streets of Kolkata, a relentless eight-year search for a missing child becomes a gripping puzzle of grief and guilt in this atmospheric thriller. Amitabh Bachchan delivers a haunting performance as John Biswas, a grandfather whose life has been consumed by the unsolved kidnapping of his granddaughter. When a strikingly similar crime occurs, it reignites his desperate quest for answers, pulling him into a tense alliance with Father Martin, a guilt-ridden priest played by Nawazuddin Siddiqui, and Sarita Sarkar, a determined police officer portrayed by Vidya Balan. Directed by Ribhu Dasgupta, the film masterfully weaves together their fractured narratives, each character driven by a personal demon, as they race against time to decipher a trail of cryptic clues before history repeats itself. A moody and suspenseful journey, the story unfolds with palpable tension, exploring the shadows of a past that refuses to stay buried and the fragile hope for redemption.
