A twist in the story happens and he gets married to another girl (Yogeeta Bali).
After a long time he meets Sharmila, who has changed and became a prostitute.
And in time of crisis, she helps him.
The movie has done fairly well at the box office and the acting of Sanjeev/ Sharmila is one of the highlights in the film.
Anyway, there seems to be some misunderstanding in the credits as Parveen Babi is not part of the cast; nevertheless, she acted in a movies called "Charitra" not Charitraheen.
This is one of the movies that seem to have never been released on Video or DVD.
