Kristen Stewart and Dakota Fanning pop pills, pee on guitars, make out with girls and kick all kinds of ass while on stage performing as Joan Jett and Cherie Currie -- two members of the 70's band, The Runaways. The teenage girl group is brought together through their shared love of music and their equally miserable lives. They're like feral children set free on the road, and things stay wild. The girls have to contend with bottles being thrown at them, a verbally abusive and sadistic manager and male rocker machismo while on tour. Whatever gets dished out, the ladies take it like pros and prove they can party like rock stars in the process.
