Formed out of the collapsing Students for a Democratic Society in 1969, the Weathermen declared war on the United States government and set out to bring the Vietnam War home through bombings of the Capitol, the Pentagon, and a string of banks and police stations. Sam Green and Bill Siegel's film builds its account from new interviews with former members including Bernardine Dohrn, Bill Ayers, Mark Rudd, and Brian Flanagan, who describe the group's turn from campus protest to underground militancy, alongside period news footage, FBI surveillance material, and photographs from the group's decade in hiding. The 1970 explosion in a Greenwich Village townhouse, which killed three of their own members while they built a bomb intended for a dance at Fort Dix, marks the film's turning point, after which the group pulled back from targeting people and toward destroying property. Decades later, several of the same activists reflect on what they did and did not accomplish, and whether they would do it again.
