Tina O'Kane hates her new freedom and tries her best to get back inside... but will she end up on G-wing or on another wing? Bev and Phyl plan to teach Bodybag a lesson. Top Dog Natalie Buxton is rubbing up her fellow inmates the wrong way.

Jim uses all his manipulative skills to get himself out of jail, but will Di realsie he is using her? Everyone on G-Wing is up in arms about the extortion racket Natalie Buxton and her sidekick Darlene Cake are running. Jim blackmails Neil Grayling into giving him the Wing Governor's job, and starts by sacking the two Julies from the kitchen. Phyl and Bev jump at the chance to replace them, but they're unprepared for all the hard work. Sylvia is sure that she has a mysterious illness - Dr Nicholson is unterested until a letter arrives for Sylvia...!

Jim is desperately trying to avoid sex with Di - but how long can he hold her off and what lengths will he go to not to have children?! Natalie Buxton seems to have everyone at Larkhall in her debt, she has even scored a cushy job in the library - the perfect place to attend to Jim's needs. She is far from discreet though, which infuriates Di! The two Julies get permission to open the G-Wing hair and beauty salon but aren't very optimistic about the idea. Naive Arun walks into a violent trap set by Natalie and Janine. Dr Nicholson is still fawning over Sylvia Hollamby.

Natalie and Darlene demand some beauty treatment - but the two Julies get their own back. Phyl and Bev have a scam going with the bakery delivery man. Malcolm proposes to Sylvia - who is ecstatic, little realising that it's her cash he's after.

Arun has a dark secret she is desperate to keep under wraps. The Costa Cons' buns and booze scam is about to be exposed. An elderly nun arrives at Larkhall and gets thumped by Natalie Buxton - but Sister Thomas seems to win the other girls round with her plans to help children in Africa. A codicil in Sylvia's aunt's will bars her from marrying if she is to inherit the house.

New inmate Pat Kerrigan arrives at Larkhall, and is desperate to make sure that the Sister Thomas gets all thats coming to her... and Pat isn't exactly keen on bully-babe Natalie Buxton... Could this be the fall of one of Larkhall's evilist Top Dogs? Sylvia and Malcolm are tying the knot... Malcolm's already splashed out on the Wedding and Honeymoon... little does he know that Sylvia is now peniless, due to a bizare twist in her Aunt's will saying Sylvia will only inherit money if she stays single.

Everyone knows that Arun is a transexual, and the knives of G-Wing are out together. And when Arun's thoughts turn suicidal, will there be a saviour for her?

Arun’s transfer is halted after Pat and Natalie’s fight. Tina uncovers Phyl and Bev’s scheme, while Di’s marriage collapses and Fenner is furious she’s taken baby Dylan despite having no idea how to care for him.

Jim ends his marriage to Di after discovering her lies. Bev saves Phyl from sleazy delivery man Frank’s attempted assault, and the two seize a chance at freedom by hijacking his van and kidnapping Tina, who saw the attack. In Spain, they catch Malcolm about to inject Sylvia with poison, and Phyl shoots him dead.

It looks like Fenner is about to get his comeuppance. He's the only PO present in the hanging cell when the girls of G-Wing go to lay flowers in memory of Yvonne – will a prisoner or a fellow screw get their revenge on evil Fenner? Bev returns to Larkhall and is attacked by Natalie, while Phyl remains on the run.

The atmosphere at Larkhall is euphoric – Jim Fenner (Jack Ellis) is dead! He was brutally killed in the hanging cell – and his wife Di (Tracey Wilkinson) is the first to discover his bloody body.
