Har Ghar Kuch Kehta Hai is a Hindi television serial that aired on Zee TV from 16 July 2007 – 18 April 2008. It was based on the story of 3 girls: Prarthna, Sidhhi, and Sanskriti. Even though they all have different lives and a different outlook of life, destiny is not always on their side, and when the unexpected happens their dreams, hopes and desires come crashing down.

First, the story focuses on the lives and different belief systems of the three main protagonists - Prarthana, Siddhi and Sanskriti.

Prarthana (Rati Pandey) is an orphan nurtured by her uncle and aunt. Her only desire is to have a traditional arranged marriage into a happy joint family. Prarthana hopes that one day she will walk into a house that is full of warmth and love.

Prarthana's cousin Siddhi (Aanchal Anand) is a vibrant and independent girl who has lived abroad most of her life. Siddhi cannot understand the concept of an arranged marriage, nor can she tolerate being surrounded by people all the time. She believes that one must marry one's true love.

Sanskriti (Amrita Prakash) is a model by profession, very straightforward and blunt in her attitude. Sanskriti can't understand the concept of marriage at all. She doesn’t believe that marriage can hold two people closer than love can. She vouches for a live-in relationship.
