The film won the 1981 Filmfare Best Movie Award. The lead actress, Rekha, won her first Filmfare Best Actress Award for her role as Manju Dayal (she was also nominated for a role in the film Judaai that year). The movie was remade in Tamil as Lakshmi Vandhachu and in Malayalam as Vannu Kandu Keezhadakki.
Middle aged Nirmala Gupta (Dina Pathak), wife of Dwarka Prasad Gupta (Ashok Kumar) and mother of four, was a disciplinarian and runs her household on rules. Everyone, including her husband follow her rules though they don't always approve her ways. She even selects wives for her sons herself and now selects Anju for her second son.
Anju, Manju (Rekha) are the daughters of rich widower Ram Dayal (David). After wedding, Manju comes to stay with her sister for some time. Being a playful and naughty girl she immediately gets the disapproval of Nirmala. But her third son Inder (Rakesh Roshan), a young doctor slowly grows close to Manju.
Manju also attracts the attention of Dwaraka Prasad who was a fun loving fellow himself. He feels relieved with the presence of playful Manju after living for long time under the controlling behavior of his wife. Manju gradually gains the trust of everyone in the house except Nirmala.
One day, she performs a small play highlighting the tyranny of Nirmala over other family members. Nirmala was not meant to be at house but she accidentally watches it. She gets hurt as everyone thinks of her as a disciplinarian though she does everything for the well being of family. Moreover the fact that everyone felt free with Manju an outsider, but not with her hurts her more.
Manju tries to apologize but Nirmala wouldn't talk to her. Dwaraka Prasad, seeing her adamant, gets emotionally upset and rants her, which further leads to his heart attack. Nirmala gets tensed as everyone except Manju left home for some function. Manju acts timely and saves Dwaraka Prasad. At last, Nirmala understands Manju's character and she too approves of her. In climax Manju and Inder get married.
