For two years, writer/director Anthony Scarpa followed female rockers Betty Blowtorch as they blazed across Los Angeles' rock scene with their ferocious sound, brash lyrics and a pyrotechnic stage show that was literally explosive. Along the way, he captured the band as they nearly got signed by a major label, toured non-stop and disbanded following the tragic death of lead vocalist Bianca Butthole. Includes interviews with Vanilla Ice, Guns N' Roses guitarist Duff McKagan, Lit's Kevin Baldes, and Black Flag's Dez Cadena. 108 min.
