As investigative journalist Alka dives deep into the realm of social justice, she encounters Amol Dwivedi, a groundbreaking advocate for acid attack survivors. Their mutual commitment to instigating change sparks a connection that leads them to Malti Agarwal, portrayed by Deepika Padukone, a valiant survivor on a mission to combat the brutal practice of acid attacks. Inspired by Malti's indomitable spirit, Amol offers her a position at his organization, initiating a transformative journey for all involved.
Fast forward to April 2005: Malti's world shatters when she becomes a victim of a horrific acid attack in the lively streets of New Delhi. The authorities act swiftly, prompted by the accounts of Malti and her boyfriend Rajesh, as they point to Basheer "Babbu" Khan, played by Vishal Dahiya, a family acquaintance, alongside his sister-in-law, Parveen Shaikh. As the police close in, they trace Babbu's phone signal, leading to his apprehension. During this crisis, Malti undergoes numerous grueling surgeries to reconstruct her ravaged face.
While navigating this turbulent period, Malti's mother finds refuge working for Shiraz and skillfully utilizes her connections to aid in financing Malti's medical expenses. Archana Bajaj, played by Madhurjeet Sarghi, joins the fight as a seasoned attorney dedicated to championing Malti's case, shedding light on the outdated laws that enable these atrocities. A chilling discovery reveals that acid attacks are treated under the same penal code as water-boarding, resulting in shockingly lenient punishments.
The courtroom drama unfolds like a slow-motion nightmare, with evidence of Babbu and Parveen's guilt emerging from eyewitness testimonies and physical signs of their atrocities. Despite the strong case against them, Babbu is granted bail, allowed to return to his life unscathed. Yet, this only strengthens Malti's resolve, transforming her into a passionate advocate for justice. Teaming up with Archana, they prepare a petition to demand vital legal reforms.
Meanwhile, Malti's brother Rohit receives a heartbreaking diagnosis of advanced intestinal tuberculosis. As time passes, the courtroom saga reaches a turning point in August 2009, when Basheer is sentenced to ten years, and Parveen receives a seven-year term. However, both individuals swiftly appeal their convictions to the High Court.
Malti's relentless advocacy leads to significant outcomes: she galvanizes support to secure funds for treatment and legal action for other acid attack survivors. Her unyielding dedication culminates in a historic victory as the penal code is revised, recognizing the severity of these abhorrent crimes. Over the years, Malti's influence expands, earning her recognition as the face of acid attack survivors, inspiring many with her story. In the midst of this transformation, she forms a profound bond with Amol, whose love for her becomes a symbol of hope in a world forever changed by her traumatic experiences.
As the truth of the attack unfolds, it becomes clear that Basheer's dark motives, fueled by jealousy and aided by Parveen's treachery, culminated in the cruel assault on Malti. The legal system ultimately delivers justice as the Delhi High Court dismisses Basheer's appeal in October 2013, ensuring the assailants remain imprisoned. However, the film closes on a poignant note, as another acid attack occurs in December 2013, a stark reminder of the persistent issue of acid violence. The narrative highlights a grim reality: even with stricter laws and heightened media attention, the alarming frequency of these brutal crimes has not decreased, primarily due to the ongoing availability of acid on the black market in India.
