Compelling and sensitive as her stories are, it is not surprising that director Meghna Gulzar turns to father Gulzar to do justice to them with his songs. For Chhapaak, the legendary lyricist-writer penned a special poem, Ab ladna hai. The promotional video shows Deepika Padukone giving voice to Gulzar's inspirational words as she calls on society to bring about a change in its mindset.

Meghna, who brings the journey of acid attack survivor Laxmi Agarwal to life, believes that Chhapaak is as much a story of human courage as it is about changing our attitude towards survivors. "Ab ladna hai is a poem written by my father specially for the campaign. Chhapaak highlights that a lot needs to change [with regard to] acid attack survivors and their place in our society. And that change can start from an individual level. Any kind of transformation begins with a small step."
