Division 4

Yarra Central police battle a crime wave of thuggery, hold-ups and the theft of $20,000 worth of goods by a mystery gang. Investigations reveal the culprits as 'The Soldiers', a re-united former teenage gang whose members have just finished serving jail terms. Sen. Det. Banner's pregnant wife, Joy, dies during premature child-birth brought on after being terrorised by a member of the gang.

Yarra Central police are confronted with a series of reports about a bad detective. Their investigations lead to an impostor, a former policeman, who is blackmailing a solid citizen caught in the office secretary trap, belting people around with unrestrained sadism, and leading two romantic lives.

19-year-old Kay Dixon is attracted by the glamorous life of big-spending racketeer Max Foley, who tries to set up a floating cabaret. Kay finds herself in the ugly world of prostitution, exploitation and violence with no apparent way out. Police investigate Foley when a criminal associate of his is bashed.
