Denny vows to get revenge on Snowball. Babs tries to adjust to being deaf. Al and Tina plot to get a pardon like Cassie and Roisin. Sylvia and Bobby's lives is turned upside down when they are declared bankrupt. Snowball continues to try to escape to be with Richie.

Sylvia is left distraught by Bobby's actions. The Costa Cons, Phyl Oswyn and Bev Tull, arrive at Larkhall with a suitcase full of gin bottles and are immediately disgusted by the squalid conditions on G-Wing.

Shell goes into labour. After being forced to fend off Colin Hedges' advances, Shell threatens to blow the whistle on Fenner and his pimping scheme, a decision which ultimately brings about disaster. Sylvia becomes the Costa Cons' latest sucker. Di uses "Gnasher" to get at Neil. The privatisation team arrive and upset the prisoners and some officers alike. Snowball makes another attempt to see Richie.

Di is finding life with Neil increasingly frustrating, and when he starts entertaining his one-night stands at the marital home, it's the last straw. Sylvia cuts all her connections with Phyl and Bev.

Snowball attempts to convince Neil that she has changed. Di plans to get pregnant, with the help of Neil's boyfriend. One of Phyl and Bev's many business ventures comes to light when Colin discovers the drugs stash hidden behind their mirror, but given his own little habit, it's unlikely that he'll be shopping them. Also, the Costa Cons' have another plan for booze, in the garden.

Fenner plans to set up Yvonne but Colin puts a stop to it. The presence of the media and a celebrity guest at HMP Larkhall gives the women a perfect opportunity to make a very public protest about the prison's forthcoming privatisation. Phyl and Bev are transferred to an open prison. Di's plans for pregnancy are a success. Snowball and Richie make a pact to die together but only one of them dies.

Julie S finds a lump on her breast and worries that it could be cancer. Colin escorts Yvonne to Richie's funeral and is placed in a very difficult position when Fenner plants a bag of cocaine on her upon their return.

Julie S struggles to come to terms with the reality of her masectomy and the prospect of a debilitating course of chemotherapy. Colin tells Karen about Fenner setting up Yvonne. Yvonne and Colin grow closer. Neil is adamant on kicking Di out, despite her being pregnant.

Karen persuades Neil to take Snowball out of solitary confinement in the hope that it will lift her spirits, but all Snowball wants is to be reunited with Richie. Yvonne is roped into protecting Snowball but she helps her to be with Richie. Fenner becomes Tina's knight in shining armour when he moves her out of the Four Bed Dorm away from nasty Al and Buki. Di's infidelity is revealed when she and Neil are tested for syphilis.

Snowball's suicide note makes some serious allegations against Fenner, which in light of the accusations made against him by Karen and Helen could get him into serious trouble. Di has her pregnancy terminated but doesn't inform Neil or Tony. Fenner and Tina plan to set up Yvonne. Karen is sacked by Neil.

Karen and Neil come to a compromise. Di and Neil reveal their split, in which Neil outs himself, and plans for surrogacy. A familiar face is welcomed back to Larkhall as old-timer Noreen Biggs arrives back on G-Wing. Unfortunately, she won't be enjoying Her Majesty's for long as she hasn't got long to live. Noreen tries to talk Tina round that Fenner is using her but Yvonne makes her see the light.

Julie S returns to Larkhall. Phyl and Bev are transferred back to Larkhall. Denny shows off her talent for art. Legal proceedings begin for Al, who is up for life for murdering Virginia. Henry quits and plans to marry Babs. Fenner breaks into Karen's flat and sees all of the evidence she's amassed against him. Deciding he must take action, he sneaks out with her car keys, coat and a bottle of alcohol. Karen is arrested the following morning.

Di becomes Wing Governor. Yvonne plans to get rid of Fenner for good. Bev and Phyl forge some of Denny's artwork. Buki finally meets her son, Lennox, with the help of Christopher Biggins. Di and Fenner go on a date and get intimate. New inmate, lifer Kris Yates arrives at Larkhall and makes a big impression on everyone, so much so that new officer Selena Geeson requests that she be Kris' personal officer.

Di fakes a miscarriage. Denny's planned art exhibition suffers a setback as a result of Phyl and Bev's eye on the bigger picture and the money they will squeeze out of their protege. Kris reveals she has an escape plan but Yvonne does not want to be a part of it. Yvonne's plan to fix Fenner goes into effect.

Babs and Henry get married but Henry's brother leaves when he objects. Buki is looking forward to her release and Denny is transferred to an open prisoner. Yvonne gives into Kris and makes a bid for freedom by slipping into the cavernous depths of the prison, but Fenner is hot on her heels, intent on sorting her out once and for all, and in the most horrific manner imaginable.
