Kathleen Hanna, lead singer of the punk band Bikini Kill and dance-punk trio Le Tigre, rose to national attention as the reluctant but never shy voice of the riot grrrl movement. She became one of the most famously outspoken feminist icons, a cultural lightning rod. Her critics wished she would just shut-up, and her fans hoped she never would. So in 2005, when Hanna stopped shouting, many wondered why. Through 20 years of archival footage and intimate interviews with Hanna, this documentary takes viewers on a fascinating tour of contemporary music and offers a never-before-seen view into the life of this fearless leader.
