'Podger Pam' arrived on G-wing's Lifer's Unit, to the alarm of the other inmates. Helen Stewart suspected that her mental state had been horribly misdiagnosed so brought in new prison doctor Thomas Waugh. Karen and Helen went to see Simon Stubberfield about Dr Nicholson's incompetence and got him sacked. The two Julies discoved a stray cat hiding in the prison bins and later discovered it was female when it gave birth to kittens. Josh had an eventful induction period as a trainee PO. Di discovered Josh was living with Crystal. Shell contiuned to taunt Jim, who was still scared of her. The tension between Jim and Helen reached new heights when Jim tried to assert his power by sexually assaulting her!

Crystal is on a hunger strike to protest about her drugs test results and, after a retest is proved right! - Josh then realises what Di did and prepares for a confronation! Jim was horrified to learn that Helen was the governing governor, replacing Simon Stubberfield! Helen officially appointed Dr Waugh as new prison doctor and seemed to get on really well with him. Josh and Crystal got 'married' in the prison chapel in a service conducted by Babs. Nikki received news that her appeal was being transferred to the high court, meaning she had a good chance of being successful. The Peckham Boot Gang made a noisy arrival at Larkhall but what wing will they be on?(!) After a heavy confronation with Josh about the drugs tests, Di took out her violent anger once again on her mother, and the next day after being called ""sick"" by Josh, spiralled out of control - after being taken home by Jim, she was horrified when he discovered her badly bruised, neglected mother in her house!

The Peckham boot gang arrives on G-Wing, causing chaos! Nigerian prisoner, Femi, can't speak a word of english and a peaceful protest about her treatment, led by Nikki, goes horrible wrong after the Boot Gang turns it into a full-scale riot! Charlotte Myddleton is shipped out to an open-prison. Al begins bullying Shaz but gets more than she bargains for from Yvonne - will Al and the rest of the Boot Gang ""waste her""?! During the riot, a new prisoner, Caroline, catches Nikki's eye. Violence erupted further when the screws, in full riot uniform, attempted to put the inmates into their cells! Helen was furious with Nikki after Sylvia told her about her envolvment with the 'peaceful protest'!

The riot finally ended peacefully because Nikki locked the Peckham boot gang in their cells - sadly for her though, Helen told Nikki that their relationship was over because of the part she had played in the chaos. Nikki then took an interest in new prisoner Caroline. The Julies argued over their plans for the future now that Julie S had met Trevor again but to their horror, they were re-arrested outside the prison gates for past crimes they had committed while working for Virginia O'Kane as 'The 2 Trudies'. Helen seemed to be yet more friendly with Dr Waugh. Femi was moved to E-Wing with Fatima, an english-speaking Nigerian prisoner. Nikki was perplexed as to why Helen was telling her to ""be careful"" of Caroline but found out from Maxi that Caroline's crime wasn't fraud...she was in prison for sexually abusing children!!

Shaz was bullied again by Al. Di Barker had a sexual encounter in the toilets with Gina Rossi's boyfriend Mark. She lied perfectly to cover her tracks until the end of the episode, when she couldn't hide how hurt she was when Mark said that ""She meant nothing to him"" - A distraught Gina then told Mark she was pregnant! The Julies returned to G-Wing...and so did Virginia O'Kane! Josh continued to ignore Di. Virginia's disability proved a challenge for the officers. To Maxi and Al's disgust, Tina seemed to take a shine to Virginia. Jim, as corrupt as ever, offered to collect Virginia's brothel money for her...for a 50% share of course!...

Jim began his 'after-hours job' collecting money from Virginia's brothels. Helen was determined to prove that Jim is unfit to work with female prisoners and was very happy when Yvonne told her about the job he was participating in for Virginia. After yet another arguement between Helen and Jim, Karen made it clear to Helen that she was on Jim's side. Di spread lies about Gina. Virginia, while alone in her cell, stood up to look in the mirror, proving that her disability was a lie. Shaz asked for a transfer to the lifers' unit to get away from Al, but Dr Waugh suggested an unorthodox way of boosting her self-esteem. Crystal received the date for her court appearance. Gina and Di came to blows over Mark, with tragic consequences. Helen and Dr Waugh went to the dog races together and later, at his flat, shared a kiss!

Josh received a surprise package from Denny that could prove Crystal's innocence. Jim told Nikki that Helen is now seeing Dr Waugh - Something Helen didn't deny! Virginia's disability was publically outed as a scam by Al. Helen continued to lie in wait for Jim at Virginia's brothels - she finally found him and told him she wanted his resignation letter or she would tell Karen and area. Jim blackmails Di into helping him find evidence about Helen's relationship with Nikki and is overjoyed when he finds in Babs' diary about Nikki's escape. Defeated by this new evidence, Helen has no ammo against Jim and is blackmailed by him to resign. Crystal was found guilty because Karen gave her a bad character statement - this was because Sylvia's stolen clock (remember that?) was found and returned to Karen!

On the day of Nikki's trial, Fenner tries one last time to jepordise her chances by trying to blackmail Di into putting a scalpel into Nikki's bag - luckily, Di refused as they left for court. Virginia O'Kane received a hostile reaction from all the girls except Tina Purvis, who was beaten up by her sister for being so sympathetic. Back at the courthouse, evidence has been given and the jury have their verdict - Nikki's sentence is reduced to three years for manslaughter...time she has already served so she is a free woman! As Di entered the bathrooms to check things are OK when she saw the lifeless body of Virginia - with Yvonne standing nearby...is she capable of murder or has Fenner set her up? In sunny Spain, we finally catch up with escapees Shell and Denny - the Spanish police have found them but we are left to wonder whether they survived after jumping into the sea to escape! In the final scene Nikki was in a club with Trish but no Helen - she walked sadly outside and heare
