Marie stops at nothing to see that her plan go through, and with a fatal outcome and with nothing more to lose will Marie's plan to escape be successful, who lives and who dies?, and will the prison ever be the same again?

Ferguson is losing control, and the walls are closing in. Fletch and Vera band together in an attempt to overthrow the Governor, while Bea discovers the final piece of the puzzle to help solve Harry's murder. Meanwhile, Franky is preparing for her release. But when Jess makes a sudden, drastic move, all plans are thrown out the window and the stage is set for a dramatic showdown.

As Bea and Allie take their illicit affair further, Bea finds herself uncharacteristically tentative and vulnerable.

Bea awakes blissfully happy after a night with Allie but it is the eve of Ferguson's trial and the Freak has been relentless in putting the final touches to her scheme for freedom and exoneration. Liz becomes convinced of Sonia's innocence and then Don puts an offer to Liz which could change her life. Maxine is committed to the chemotherapy and her prison family rallies around her.

Liz makes a desperate attempt to see her son, whilst Jake becomes concerned for Linda when she's still being manipulated by Sean. The women turn on Marie, as Marie prepares to make a bold plan to be exonerated for her crimes.

In the final countdown, the fate of everyone is uncertain.

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.

When Fletch follows Bea's instructions to use Jianna as a means to unsettle Ferguson, he unwittingly sets Vera up to take the fall. Vera, for her part, is consumed with a desire for revenge against Lucy for infecting her with Hep C. Meanwhile, Bea's manipulations of Fletch result in him finally recovering his memory and alerting Will, who is on the verge of being arrested for Harry's murder, to the truth behind Ferguson's manipulations. As the forces align against Ferguson, she begins to unravel, realising she is in a fight of her life, professionally and personally.

With Bea and Allie finally out as a couple, Kaz forms an alliance with Tina's Asian crew to help take Bea down. But when Jake smuggles a new batch of drugs into the prison for Tina, Bea gets wind of the stash and orders Tina to flush the gear. Tina refuses, citing Bea's weakening power-base, and her alliance with the RRH.

When Ferguson's pet goldfish dies, she identifies her lack of emotion at the death as a potential weakness, rather than strength. But in seeking a renewed connection with Doreen, Ferguson unwittingly makes herself vulnerable when she calls Doreen - Jianna. Bea sees this as a possible chink in her armour and tasks Doreen with uncovering the truth behind the name.

Against Vera's wishes, Ferguson is released into general. The women are out for blood but Vera confines Ferguson to her cell for safety reasons. When Ferguson challenges Vera's decision, she's left bewildered and wondering whether Ferguson has a death-wish. As always, Ferguson has an endgame but will she live to accomplish it?

Ferguson, having found protection in Kaz's crew, cunningly blames Will for her brutal ganging, a move which only strengthens Kaz's support for her. When Bea defends Will, it backfires dramatically. She is painted as a screw-lover, and rapidly begins to lose the support of the women. The first ever conjugal visit takes place at the prison, and Boomer shamelessly attempts to impregnate herself to her deadbeat ex-boyfriend, Daz. Meanwhile, Maxine is diagnosed with breast cancer and can't bring herself to tell the other women.

Ferguson is rattled when she discovers that Bea will be supporting Jesper’s evidence in court. Meanwhile, Bea seems to be losing control of the women so she forces a prison-wide vote to end the debate. Vera is privately determined that Bea maintains control and interferes with the votes, cementing Bea’s power. When Kaz gets sentenced for 12-years, Ferguson unveils her plan and urges Kaz to help her. In return, she’ll take out Bea Smith.

Bea struggles to recover in the wake of her attack. Ferguson returns from the burns unit and is placed in a medical hold under the supervision of Jake. Maxine is back after surgery and finds herself in the crossfire of huge tension between Boomer, Liz and Sonia.
