Episode 326 involving the life and death struggle between Bea and the Freak as a fire rages throughout the prison is the best episode of Prisoner ever made bar none IMO.
I too also really enjoyed the episodes where the Wentworth girls are working in Andrew Reynold's apparels factory making garments for the dodgy businessman and the resulting Kay White aftermath story in Wentworth.
The look on Governor, Erica Davidson's face when Vera informs her that the man she has just spent the night with is nothing more than a common day crook is priceless!
