Movie Story : Teen Aur Aadha follows a single house across three distinct eras. Fifty years ago, the building is split between a school and a family apartment, where a young boy struggles with the pressures of school life while sharing a cramped room with his paralysed, bitter grandfather. The old man has secret plans for the boy's twelfth birthday, which falls on a leap year. Two decades later, the same walls hold a brothel, where a young courtesan faces her first client, a man who can only perform when bound by a paid arrangement.
