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.

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.

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.

Franky’s parole hearing is brought forward but will she be granted a released? Meanwhile, Doreen faces an agonising choice.

Following the riot, Bea must balance an uneasy peace with Ferguson with the needs and expectations of the women. Ferguson wants to stamp out drugs inside the prison and for obvious reasons Bea finds herself on common ground with the Governor. But when it becomes clear that Ferguson wants Franky's head for it, Bea must wonder if, rather than help her cement her position as Top Dog, it may indeed be a ruse to undermine it. Meanwhile, Liz has a difficult reunion with her daughter Sophie and is unsure when Doreen proposes she be the alternate carer when the baby comes. Will is in a happy place and seems to finally be able to put the past behind him is shocked when he is the focus of a murder investigation.

Vera's faith in her Governor is put to the test. Meanwhile, Bea finds herself at her lowest ebb as she realizes her war against Ferguson is having an effect on those closest to her.

After being slotted for an aggressive confrontation with Ferguson, Liz's world is rocked with the arrival of a new prisoner. Franky has commenced her sessions with Bridget, and in a candid moment admits to a desire for revenge against Bea. When Bea is shivved in the yard, Franky comes under suspicion, but Bea quickly realises Jodie, freshly released from the Slot where she was terrorised by Ferguson, was behind the attack at the Governor's behest.

Ferguson is blindsided by Jodie’s complaint to the ombudsman. Channing attempts damage control, but Jodie’s accusations of brutality promise to be very damaging for the Governor

Bea struggles to accept that she had a psychotic episode, despite the CCTV evidence. When her blood is found to have traces of LSD, she realises that her attacker caused the meltdown. She smuggles evidence out of the psych unit, understanding she'll need to play the long game if she's going to defeat Ferguson. Meanwhile Bridget struggles to force Franky to accept that she has an emotional block. But when she challenges Franky to talk about her mother, she elicits a confession she wasn't expecting.

Franky's under fire. With her supply cut and her powerbase decimated, she's on her own when prisoners come after her to claim what they're owed. Bridget identifies Franky as someone she could really help, but Franky refuses to engage, venting her frustration by trashing the Education Unit. Meanwhile Bea is concerned at the police interest in Will, and shocked when he makes a startling confession.

As Fletch makes a difficult return to work at Wentworth, he is troubled by an incident that leads him to suspect his accident was no accident at all.
