The script held in the Crawford Collection in the AFI Research Collection contains the following character notes (excluding regular characters):
'HERB DOHERTY About thirty. A cheeky little crim who turns fizz because he has fallen for Policewoman Margaret Stewart. He claims he is a reformed character and needs Marg to keep him on the straight and narrow. He is Irish, has a quick inventive mind, can usually talk his way in and out of situations. Although he seems inoffensive and harmless, he causes more than his share of trouble. And despite a string of minor convictions in his past, he is likeable - with a charm all his own.
'PATRICK BENEDICT ANDERSON Forties. A hardened crim, (previous convictions for burglary, assault and robbery, armed hold-up, assault with a weapon) who has organised a smash-and-grab with two of his old cronies. The job they pull is well-planned and executed. The only flaw is Herb.
'ROBBINS Thirty-forty. He is the gunman in the team, employed to cover the others in a raid or take care of any unnecessary violence. Lives by the criminal code, sets out to avenge Anderson when he is taken by the police. Tough and without compassion. Blasts a man down with a shotgun in a second robbery.
'SMITH Forty-fifty. His trade is stealing and driving getaway cars. He does his job well, but is not over-bright. He joins Robbins in tracking down the man who betrayed Anderson - although he is not as involved or as vicious as Robbins.
'JUNIE MULLINS Late twenties, early thirties. She is a former prostitute who is living with Anderson. Attractive, well-groomed, but tough underneath. She likes the best of everything, which Anderson is able to supply - until he's caught. The crims use her place as a base.
'SAMMY JUDD Roy Lyons.
'DAWSON Sixties. Wears an old suit and tie, but this is a front. Has a shrewd mind and is an able fence.
'GOLDBERG Forty-fifty. (Possibly younger) A jeweller whose shop is raided by the smash-and-grab gang. Excited when we see him and aggressive with the police.
'JOSEPHS A butcher who sees the smash-and-grab from his shop and gives information to the police.
'DRIVE-IN BAR ATTENDANT Twenties. Held up by Smith and Robbins, gunned down by a shotgun blast.
'GIRL An attractive girl - around twenty - who ministers to Herb in the final scene.
'FINGERPRINT MAN Robert Schroeder.
'FIRST CONSTABLE SHEPHERD George Cunningham.
'EXTRAS Several pedestrians.
'EXTRAS A few drinkers.'
