The story of Teen Aur Aadha is based on a house and its inhabitants across three different eras. 50 years ago, the house was divided between a school and an apartment, which housed a boy, struggling to cope with the pressure of the pre-pubescent school life and his paralytic grandfather. 20 years later, the house becomes a brothel, where a young concubine is dealing with her first client. 30 years later, the house is home to an elderly couple who live a merry life reminiscing their lives.
