Prisoner: Cell Block H

Her chance of parole gone, Bea plots to get back at Joan. At the halfway house, Alan is dead but Sara has survived. Bea gets Barbara to tell Joan the diaries are hidden in isolation. Chrissie starts a fire in the library to distract the screws. Unknown to everyone, Margo chucks a molotov cocktail into a store cupboard full of turps. Bea attacks Joan in isolation as Wentworth burns beneath them. Barbara tries to get her diaries from Erica's office but is overcome by smoke. Paddy climbs through the air conditioning to get out.

Joan and Bea are trapped on opposite sides of a security gate - and Bea has the keys. Bea refuses to unlock the gate, saying she's ready to die - and Joan's going to die there with her...
