Mala works as a school-teacher. One day her friend confides in her about her love affair with the son of a wealthy man, who has been intimate with her, but now is marrying someone else. Mala accompanies her friend to this male’s wedding, disrupts it, and eventually ends up getting it cancelled. The groom’s brother, Raja, is enraged and insults Mala, in response to which she slaps him. Enraged all the more, Raja seeks Mala out, and in the presence of her pupils, brutally slaps and then rapes her. The police get involved and Raja is arrested.
Raj’s dad, Rai Bahadur Diwanchand, attempts to give some money to Mala’s guardian, Gyani Kartar Singh, who refuses to accept it. The court case proceeds; the judge, overcome by Mala’s evidence, finds Raj guilty, convicts him, and orders that he marry Mala in the next twenty-four hours. Raj attempts to kill Mala are in vain, and they get married without great pomp and ceremony. After the marriage, Rai Bahadur goes overseas and leaves his family, especially his elder daughter-in-law, Sharda, to deal with Mala and ensure that she is belittled, tortured, and eventually driven out of their house. Sharda’s younger sister tries to make Raj get trapped in her love, but she fails because Mala insults her and goes to her sister.
