In August 2018, Thunberg, a 15-year-old student in Sweden, started a school strike for the climate as her question for adults was, if you don’t care about my future on earth, why should I care about my future in school? Within months, her strike evolved into a global movement as the quiet teenage girl on the autism spectrum becomes a world-famous activist.  

The documentary follows Greta’s heroism and passion in fighting for climate change.
