Director of "Laaga Chunri Mein Daag"Pradeep Sarkar looks forward to securing a hit with "Lafangey Parindey", an unusual love story about a blind ambitious girl and a street fighter that releases Friday.

Produced under the banner of Yash Raj Films, "Lafangey Parindey" is about Nandu (Neil) who fights blindfolded and visually challenged Pinky Palkar (Deepika), who can dance on skates.

While Nandu is fierce and hungry to win, Pinky's ambition is to rise above all the 'losers' living in her locality and carve a niche for herself. They, along with a group of friends, set out on a journey to achieve the impossible.

Deepika calls it one of the most challenging films of her career.

"For me, this role out of all the films that I have done was the most challenging. It's not been easy. It required a lot of focus and concentration. I had to observe a lot of blind people before I could play this role, " Deepika told.

"The biggest challenge was to pretend that I was not seeing. There were no supporting tools like black goggles or a stick with me to make it obvious that I am blind, " she added.

The actress along with other cast and crew spent time with visually challenged people to understand their behavioural nuances and figure out counter actions.

The film will have some daring stunts and both the actors have performed them themselves.
