After a 12-week hiatus, due to UEFA Euro 2004, the remaining four episodes of the series were screened Monday nights and concluded on 23 August 2004.
This series introduces Eva Pope (Frances Myers), Dannielle Brent (Natalie Buxton) and Antonia Okonma (Darlene Cake), while Pauline Campbell (Al McKenzie), Charlotte Lucas (Selena Geeson) and Jennifer Ness (Kris Yates) depart the series.
Kris, still determined to follow Yvonne's route to the hanging cell, needs the help of Selena if she is to make a successful escape.
Meanwhile, two new prisoners arrive on G-wing; Frances Allen is in for prostitution, while Natalie Buxton claims she was sentenced for income tax fraud.
Hell-bent on making him pay, Fenner becomes unstable, attacking inmates such as Kris Yates and exposing himself to the entire wing and is placed under the mental health act.
Glamour hits Larkhall in the form of footballers' wife Tanya Turner when she arrives at the prison in a sweatbox.
He is determined to find ex-Wing Governor, Karen Betts, convinced that she holds the key to bringing Fenner down.
Tina and Darlene are then conned by Phyl and Bev into believing that Natalie made the rhubarb hooch that poisoned several inmates and killed Al McKenzie.
Fenner is in seventh heaven as he and Di tie the knot, but when he sees Neil and Karen entering the church clutching a big envelope, he goes cold with panic.
