When Bea is sentenced to life without parole for the killing of Brayden Holt, Ferguson makes it very clear - she owns Bea now. So when Bea uses her standing as Top Dog to hit back, Ferguson takes revenge - she slots Bea and releases Liz from Protection, exposing Liz to a brutal bashing from Boomer. But Ferguson has underestimated Bea, who starts a riot amongst the prisoners. With the prison in lock-down Ferguson has to turn to Bea to quell the riot. Wentworth isn't Ferguson's prison - it's Bea's. Battle lines are drawn.
