This documentary about the all girl rock band The Runaways, has no original Runaways music. The only music you hear is by other artists or you hear the band doing cover songs. That's because Joan Jett refused to take part in the production and refused to grant permission for the music to be used.
The title refers to an element of sexual game playing where one tries to take a partner to the very edge of their sexual or emotional limits.
Director Victory Tischler-Blue was actually a replacement member of The Runaways when bass player Jackie Fuchs left the band.
