Based on storyline in Gideon's Night. Jerry Blake (Ronald Lacey) is moving in on Frank Romano's (Ray Brooks) small business protection racket. Both are leaders of gangs of young men and trouble is brewing. But Romano's wife is unhappy with their lifestyle and uses an old boyfriend to arrange the snatch of over £400,000 of old money meant for burning. Romano joins up with Blake to do the robbery while their gangs do a fake rumble to lure the police elsewhere.
