Looking at acid violence through the lens of survivor Laxmi Agarwal, Chhapaak tells the story of a girl (Malti) coming from an unprivileged but humble background. When Malti refuses the advances made by a man twice her age, she is attacked with acid on the street in New Delhi. With her face irreparably burnt, Malti undergoes medico-social rehabilitation, a prolonged string of facial surgeries, a legal battle against her attacker, and a constant struggle to become economically independent. During this time, Malti also joins a campaign against Acid violence and comes across other victims. She forms an inexplicable bond with Amol, the founder of the campaign. Still, it is Malti`s game-changing PIL in the Supreme Court of India, with her lawyer Archana Bajaj, that inspires the Judiciary to amend the laws on acid violence. A story of the triumph of the unquashable human spirit.
