As this song is in Lights and Sounds; an album centering on Yellowcard's negative feelings towards la and stuff, I think that 'she' refers to Hollywood in this song.
And, basically, I think what Yellowcard is trying to say is that they want to get away, but they can't because in a figurative way, Hollywood is preventing them from doing so with her 'charm' and all.
Ah, may have got it wrong, but still love this song.
Yellowcard to the power.
