Bidaai is a story of two sisters, Sadhna (beautiful) and Ragini (unattractive). Sadhna is the adopted child in the family. Life is pleasant for Sadhna as she is beautiful but society is a bit rude and harsh on Ragini, who faces a lot more challenges because she is not good-looking. Both the sisters love each other immensely and are good natured but societys approach towards them makes Sadhnas life difficult as her mother starts differentiating between them. Sadhna is treated like a step-daughter in the house and feels punished for her good looks but Ragini loves her unconditionally. All-in-all, the story is about these two sisters whose 'looks' determine their happiness. This unique story embarks the journey of two sisters and makes one question the belief - Are beautiful people happier than ugly Bettys?
