In February 2018, 19-year-old Nikolas Cruz entered Marjory Stoneman Douglas High School in Parkland, Florida, carrying a semi-automatic rifle. He killed fourteen pupils and three members of staff.
In the aftermath of one of the worst mass school shootings in recent history, students from the school organised what became a global, youth-led movement, campaigning for stricter gun laws in America.
With filming beginning shortly after the shooting, this documentary follows pupils from the school, including Lewis Mizen, a 17-year-old British senior, as they take on the establishment to demand change. The film also tells the stories of some of the other students affected by the shooting.
