Before she directed Wayne and Garth in Wayne's World, Penelope Spheeris helmed this music-driven documentary about the hard-hitting Los Angeles punk scene, a film that proved so potent at its first screening that it was banned by the LAPD. Highlights include live performances by Black Flag, the Germs, X, the Bags, Circle Jerks, Catholic Discipline and Fear, plus interviews with the bands and the eXtreme fans who love them.
