[1][2] Set in Bhagalpur, Bihar, it is the story of Krishna, who rises from modest beginnings to a successful career.

[3] The show was dubbed into English and aired on Zee World for an international audience.

Her father, Vidyapati Raj, and family have sacrificed to make sure that Krishna receives the education necessary to achieve her goal.

[4] Moreover, her father's brother, Bihari and his wife Dhahati want their daughter Pinky to become a BDO and have resorted to bribes and other illegal activities to make it possible.

The family were able to marry off the eldest sister, Manisha, but never fully paid off the dowry and have hardly any to give towards Swati's marriage.

A proposal is offered and Bihari takes the opportunity to sabotage Krishna's studies of becoming a BDO and arranges for Swati to get married without a dowry with the offer of Krishna's hand in marriage to the elder widowed brother.

Babloo Singh comes up with a plan to kidnap Krishna with the help of his younger brother Pintu, who gets her to take her exams in Patna.

The mother and brother are overjoyed and they eventually move towards encouraging and supporting her in her dreams to become a BDO.

At Swati's wedding, Pintu starts to see Krishna in a new light and a fondness for her is developed.

He reveals the truth about it after admiring Krishna's perseverance and determination to follow the path of the law and not cave into bribery.

Babloo is saddened that he cannot be there for his favorite student, and Krishna is heartbroken at losing the guidance of her mentor.

However, an incident at the movie theatre where Krishna speaks out in his defence suddenly reminds him of her strong principles and character.

A sound talk from Sargum, Babloo's wife and Pintu's sister-in-law, helps remind him that Krishna is a far better person than is wife-to-be (Pinky) who stood there quietly.

Krishna, with the help of her younger sister Chanchal, eavesdrop outside the window to hear the training techniques.

Feeling that she is doing something wrong and against her own principles, Krishna opens up to the deputy collector and apologizes for listening in on the lessons without his permission.

While in the waiting room at the bus station, Krishna's bag containing her admission card is stolen.

Pintu has bribed the name-caller to bump her name up so that she is last to be called and won't miss her interview.

Krishna passes the exam and impresses the panel including the two examiners who have been bribed.

At the house she sees Pintu accidentally holds Krishna's hand when he tries to help her catch a falling file.

Devastated at the outcome of her interview, the fact Pintu rejects her, and that Krishna is getting all the attention, she attempts suicide(superficial cuts to the wrist).

The day after the engagement, Krishna, Chanchal and Ravi run into Pintu and his nephew at a restaurant by chance.

Meanwhile, Krishna decides to protest her results and goes to Patna to request that an investigation take place.

Hurt and angry, Pintu calls off the wedding, leaving Pinky heartbroken.

They experience racism problems because of Pintu's fair skin and Krishna's dark completion.

She is a corrupt woman who has illegal ownership over a huge piece land, she along with Tun Tun Singh start causing problems in Krishna's life, because of them, Krishna is falsely accused of being corrupt and given a chance to prove herself innocent.

Krishna decides to enter Pintu's house, leaving her dream to be an IAS officer.

Finally Pintu and Krishna succeed in their plan by delaying the muharath which caused the marriage not to be accepted by the rituals.

At the end, Pinky becomes very nice and Krishna gives birth to a baby girl and all the family are happy.
