Wilderness Workshop will host a screening of the movie “Wrenched,” featuring conservationist Dave Foreman, at Paepcke Auditorium at the Aspen Institute on Dec. 10.

“Wrenched” follows the work of author Edward Abbey, whose novel “The Monkey Wrench Gang” was based in part on the environmental activism of Foreman and others. Foreman founded EarthFirst, an organization that advocates grassroots involvement and sometimes civil disobedience to protect wilderness and contain human encroachment. Filmmaker M.L. Lincoln presents interviews, archival footage and re-enactments to capture the outrage of environmental activists who performed high-profile publicity stunts that made them the target of FBI infiltrators, leading to the arrests of various people including Foreman.

Foreman will sign books at 4 p.m. in the auditorium lobby before introducing the film at 5 p.m. and will lead a Q&A session afterward. Tickets are $25 in advance and $35 at the door.
