Breakout

Luna is a leader of a group called Pain and after Luna(the main character) gets into a fight too many she is sent to Golden Gate prison with two of her friends. The reason for this is that higher ups think that she will change her ways once she gets to the Golden Gate prison as the guards there are stricter and crueller to the prisoners. While she was on her way to the prison she makes a bet with another prisoner, the bet is who can get out Golden Gate prison first. The group who get's out first are the winners and losing has to disband. Which group will get out first?
