For several years, FRONTLINE has collaborated with ProPublica to investigate the rise of extremism in America. In the aftermath of the January 6 assault on the U.S. Capitol, FRONTLINE, ProPublica and Berkeley Journalism’s Investigative Reporting Program teamed up to examine how far-right extremist groups had evolved in the wake of the deadly 2017 Charlottesville rally — and the threat they posed.

The film won the George Polk Award for National Television Reporting, the Edward R. Murrow Award for Feature Documentary, and was a finalist for the DuPont-Columbia University Award. An updated version of the documentary aired January 4, 2022 and examines the latest developments and where the movement may be headed a year after the attack on the Capitol.
