The story of Teen Aur Aadha revolves around a house that has withstood three different eras. It was divided into a school and an apartment some 50 years ago where a student is struggling with his identity as a teen and is forced to share a cramped up room with his disabled grandfather. The house after 20 years is changed into a brothel where a young prostitute is trying to please her first client and has a strange way of doing so. 30 years ahead the house is now home to a 75 year old couple who still love life and live in harmony. They live a life of peace and love, which was very different for the previous inhabitants of the house.
