Matsu, known to the prisoners as Scorpion, is locked away in the bowels of the prison as revenge for disrupting the smooth operation of the prison and for her disfiguring attack on the warden. Granted a one day reprieve due to the visit of a dignitary, she takes advantage and attacks the warden again. This leads to more brutal punishment and humiliation. But the punishment gives her an oppurtunity to escape along with six other female prisoners. Their surreal flight from prison pits the convicts against the guards, the warden and each other.
