Sir Richards Mental Sanatorium is run by the strict and authoritative Dr. Khurana, along with the other two main doctors, Sunil and Tanvi Khurana, who is the daughter of Khurana. Tanvi has treated a female patient who wears no. 36 with love and proper care, rebelling against Khuranas inhumane ways of dealing with mentally ill patients. As she gets discharged, Tanvi doesnt get acknowledged for her efforts, which devastate her and since then, has become embittered and vows to never come close to any patient, especially no. 36.
