The script (which follows the escape and subsequent re-capture of two Pentridge prisoners) bears a strong resemblance to the events surrounding the escape from Pentridge Prison of Ronald Ryan and Peter Walker and the subsequent execution of Ryan.
The script held in the Crawford Collection in the AFI Research Collection contains the following character notes (excluding regular characters):
'MICHAEL XAVIER O'BYRNE Early 40's, preferably not tall, medium build, must be active. Mick O'Byrne, gaol escapee, is an egotist, becoming in his own mind, invincible. Able to drive.
'JOHN REYNOLDS Early 20's, preferably taller than O'Byrne, good-looking, well built. Reynolds is the other escapee. He's young and bewildered by the killing of the warder, bewildered by the intensity of the hunt, but most of all, bewildered by O'Byrne's manner. He comes to believe O'Byrne's self-publicity, looks up to him almost as a father. Able to drive.
'MAY CROSSWAY 25 to 30. Not beautiful, but cunning, knowing. She resigns herself to the presence of the escapees.
'BETTY KEMP About 25, more attractive than May. But dumb.
'CONST. REYNOLDS About 20, but looking younger than this. Const. Reynolds is the escapee's brother. He's painfully young, patently nervous.
