A gang of thieves are robbing the payroll of a factory and making their getaway from a passing barge.
Only DI Maguire figures out that there has been a spate of robberies next to the canal.
One of the gang of thieves gets careless spending his money on wine and women.
A man who gave the gang some inside information meets a fatal end while trying to get away from Maguire.
You need to have split second timing to jump on a passing barge.
Once again Maguire gets all the breaks, enough to barge in.
I did figure one of the gang was easy to identify despite masking his face. The small lad from the movie Hue & Cry!
