Guess this movie and you get whatever you want

The film tells the story of four petty criminals who get together to find some family diamonds which were stolen by someone who died while one of the four was interrogating him. They are all from different backgrounds and have different skills, but they are all united by their desire to find the diamonds.

Extra hint: Out of the four - one is a girl

This thread was part of Question 2 (Do you think you are a creative writer). For those who answered no, they had to describe the plot of a Hindi movie badly and post it in the Bollywood forum.

This one totally fit that description. The movie was Padmashree Laloo Prasad Yadav.
