12/24 Karol Bagh, Delhi is the address of the Sethi family. The head of the family is Mr. Rajinder Sethi who owns a shop selling bridal wear. He is a simple man who does not believe in God. His wife Manju Sethi is a practical woman who has a positive outlook towards life. Simi (Smriti Kalra), the eldest daughter, is 28 years of age and is still unmarried. Though she is soft-spoken and sweet, she is a bit plump. The second child is Anuj (Wasim Mushtaq), who works in a bank. Anuj has a girlfriend but is waiting for his elder sister to get married. The third child is Neetu (Sargun Mehta) who is happy go lucky, extremely boisterous and whose only goal is to get married. And the youngest daughter is Mili (Hunar Hali), who is street smart, bold and realistic. Presently the biggest concern in the Sethi family is Simi's marriage as she has already been rejected 9 to 10 times. As the story progresses, you get to see the Sethi family face various problems, always managing to stay together through thick and thin.
