Will Mallika get to know that Sadhana is Alekh's wife?
Bidaai is about the lives of two cousins. Dark-complexioned Ragini (Parul Chauhan) and a fair complexioned Sadhana (Sara Khan).
Sadhana's father passed away during her childhood, she grew-up with her uncle Prakashchand's (Alok Nath) family, which consists of his wife Kaushalya (Vibha Chibber) and daughter Ragini. In spite of being just cousins, Sadhana and Ragini are closer than real sisters. They are similar in every sense except their skin color as Ragini is much darker than Sadhana. It is because of Sadhana's complexion that Kaushalya is jealous of her. However, Prakashchand has never differentiated between them.
Circumstances force Sadhana to marry mentally retarded Alekh Rajvansh (Angad Hasija). Sadhana copes with the mentally retarded husband and a taunting and overbearing mother-in-law Vasundhara (Seema Kapoor). When Ragini and Alekh's brother Ranvir (Kinshuk Mahajan) fell in love, Sadhana plays cupid for them. After a lot of drama, Vasundhara agrees for Ragini and Ranvir's marriage. However, Vasundhara feels ashamed to have a dark-skinned daughter-in-law.
The story focuses on Sadhana and Ragini's lives after they are married off (Bidaai). It narrates the ups and downs in their lives. Right now, Alekh's treatment is the main concern for Sadhana.
