The film begins with a retreat, where alumni from different batches of a residential school have travelled to their alma mater for a reunion. Anabil, one of the alumnus, presently working with UNICEF India as a "child protection specialist", narrates the story of his childhood days spent in the residential school. Anabil was a shy boy who was ragged by the seniors in his residential school. He was nicknamed "Bile", the pet name of Swami Vivekananda. When he realised that he wouldn't be able to cope with the hostel life, a new monk arrives as the hostel-warden, Kanu da, and soon Anabil finds a magic diary. Both change his life.
