The punk activist collective Positive Force emerged in 1985, rising from the ashes of the Summer Revolution. This feature-length film from Robin Bell skillfully mixes rare archival footage (including electrifying live performances from Fugazi, Bikini Kill, Nation of Ulysses, Anti-Flag, and others) with new interviews with key PF activists such as co-founder Mark Andersen and supporters such as Ian MacKaye, Ted Leo, and Riot Grrrl co-founder Allison Wolfe. Spanning a 25-year period, More Than A Witness documents PF's Reagan-era origins, the creation of its community house, FBI harassment, and the emergence of a vibrant underworld that exploded into the mainstream. public amid controversies over the means and ends of the movement. In quintessential punk fashion, PF volunteers applied creative DIY tactics and radical critiques to issues of homelessness, racism, corporate globalization, sexism, and war, while struggling to constructively the conflicting dynamics and visions within the group itself.
