The film follows two friends, Joan Jett (KRISTEN STEWART) and Cherie Currie (DAKOTA FANNING), as they rise from rebellious Southern California kids to rock stars of the now legendary group that paved the way for future generations of girl bands.
They fall under the Svengali-like influence of rock impresario Kim Fowley (MICHAEL SHANNON), who turns the group into an outrageous success and a family of misfits. With its tough-chick image and raw talent, the band quickly earns a name for itself and so do its two leads: Joan is the band's pure rock' n' roll heart, while Cherie, with her Bowie-Bardot looks, is the sex kitten.
