Officer Joan Ferguson (Maggie Kirkpatrick) has been arrested for her complicity in the bank robbery executed by Rita Connors (Glenda Linscott). ‘The Freak’ was caught as she was about to leave the bank with $250,000 which Connors had hidden in the women’s toilet.
Ferguson panics once she realises she's about to be taken to Wentworth Detention Centre, where she’s made countless enemies amongst both staff and prisoners. She flips out at Officer Meg Jackson (Elspeth Ballantyne) as the latter follows the induction process: 'Do it Morris, I'm here, do it! You must think all your birthdays are coming, you must really be enjoying!'
The climatic scene from Prisoner's last episode sees Joan Ferguson arrested and sent to the prison she's terrorised for four years.
