As the new series opened, we see Fenner in Helen's office. He obviously thinks that Helen had resigned and that he was the new wing governor. Nikki looked for Helen's car to arrive...it didn't. Zandra went into labour and was rushed to hospital where she gave birth to a baby boy. Helen finally arrived at the prison, resulting in Jim being annoyed that his dreams of promotion were once again shattered. New warden Karen Betts started work - she and Jim have met before it seems. Robin promised to visit Zandra at Larkhall in the future but then took the baby and left when drugs were discovered in Zandra's cell. Zandra then lost it and ran to the prison roof, threatening to jump off! Dominic saved her from a nasty death though by nearly falling off the roof himself! Nikki told Helen that she can't control her feelings for her but Helen still denied she returns the feelings. Shell somehow got a mobile phone smuggled in, dialled a number and said ""Can I speak to Mrs Fenner?""!

New officer, Karen Betts, starts at Larkhall and reveals that she and Fenner have history. Helen is torn between duty and desire as she battles to hide her true feelings from Nikki, when she has no option but to transfer her to another prison after she slaps Dominic. Fenner discovers Shell's deceit and his anger knows no bounds but his wife wants him gone.

The police arrived at Jim Fenner's house and interviewed both him, and his wife Marilyn about Shell Dockley, and Jim's assault on her. Marilyn and Jim decided to stay together for the children's sake but Jim persuaded Marilyn to send Shell a letter, saying that she had broken up their marriage. Stubberfield told Karen Betts that he wanted her to take over as wing governor after Helen's departure. New Prison Officer, Di Barker, arrived on the wing and seems like a nice quiet girl. Julie J learned that her kids are back in the UK and wanted them to visit. Bodybag took great pleasure by refusing. Jim returned to the wing; he confiscated all the letters that he had sent Shell – now she had no evidence against him. He even told her that he loves her - just so she would lie and tell Stubberfield that she made up the allegations. She did and Stubberfield believed her. Denny's mother, Jessie, didn't show up for the visit. The Julies polished the stairs more than was necessary – Sylvia fell do

This episode picks up where series 2 ended. Jim's enjoyment in Shell's cell soon comes to an end as she violently stabbed him with the broken bottle - Karen heared his screams and called in all available staff. Despite her protests, Helen drove Nikki back to Larkhall and was reassured of her ability to do so when she heared about the mayhem on the wing. After numerous attemps to make Shell give in, The officers (now in full riot uniform) stormed into the cell and finally overpowered Shell and got Jim out. Shell was then taken down the block. Helen smuggled Nikki back to her cell and because of the mayhem upstairs, no-one noticed! As the episode ends, we see Jim flat-lining on the stretcher, with Marilyn screaming and Dr Nicholson trying in vein to resuscitate him...!

Dr Nicholson succeeded in saving Jim's life and he was quickly rushed to hospital. Sylvia, enraged at the fact that Shell wasn't being punished for her attack on Jim, decideds to take justice into her own hands - after a word with Dr Nicholson, Shell was transferred to the 'muppet wing'. Julie Saunders decided to apply to be a part of a tagging scheme so that she could see her son David's school play. Jim continued to recover well at the hospital. Sylvia excelled herself when she put Mad Tessa Spall as Shell's cellmate and, with the help of PO Wheeler, took further action by making Podger Pam attack her. Later in the week and to Sylvia's disgust, Shell was later allowed back on G-Wing - Sylvia then called on the PO's to go on strike!
