I am in search of a movie that I watched in 2008 in TV.I don't remember it's name or cast or year of it's release.A girl of around 20 lives her granny & her younger sister in the village & goes with her boyfriend to work with him in the city.After they reach the city ,the boy sells her for prostitution.Her owner forces her to have sex with varieties & collects money from them. She was stuck there for a long period with no help.Finally one day she kills her owner & was taken to prison for 10 years.After she was released from there ,she finds that her gran had died.Then she finds her younger sister.The movie was really good.Plz someone help me find it.
