Devki Sabarwal(Sridevi) is a biology teacher in a New Delhi school. Her step-daughter Arya happens to be her student. It so happens that one of the boys in the class has a crush on Arya and he keeps sending her messages—sometimes even lewd ones. On one occasion, Devki sees one of those messages and she throws the boy’s phone out of the class. Naturally, he is angry with the teacher.
At home, one can see that the relationship between teenage Arya and Devki is stressed. Arya calls her `mam’ instead of Mom. However Devki cares as deeply for Arya as she does for her natural-born younger daughter Priya.
Her husband Anand also tries to neutralize the equation between his wife and his older daughter. However Arya is stubborn.
One day Arya requests her father that she be given permission to go to a party at a farmhouse with school friends. Anand is due to leave on a business trip to USA for 10-days so he refuses permission initially. However Arya convinces him that she will be back home by midnight and he allows her to go.
At the party, Arya dressed in a smart red outfit is seen having a good time. She has a couple of alcohol shots and is dancing away. She spots a boy she has a crush on. However the boy is involved elsewhere so she is dejected.
She decides to leave the party but since her best friend is too drunk, she calls for a cab. Around the same time, the school boy whom Devki has reprimanded spots Arya. He asks for a dance. However Arya refuses. The youngster complains to his cousin Charles Dewan about this rejection. Charles, Jagan(Abhimanyu Singh), Baburam, a watchman help the youngster kidnap Arya. In the car she is physically violated and thrown out in a gutter.
A morning jogger spots her and gets her to a hospital.
