The film depicts how Satyarthi left a career as an electrical engineer and started Bachpan Bachao Andolan (Save the Childhood Movement) to rescue children from slavery. In the decades since, he has rescued more than 87,000 children and built a global movement including one of the largest civil society movements, the Global March Against Child Labor that demanded an international law on the worst forms of child labor, and the 100 Million Campaign, a youth-driven call to action ensuring every child in the world is free, safe and educated.
