Synopsis
London in the Sixties. Organized crime gangs are working smoothly but know that, when confronted by the Police, they're "banged to rights" and need to "come quietly". This cosy balance, however, is disrupted when a group of Australian criminals impersonate the Metropolitan Police and make off with the proceeds of the crimes after duping the criminals. Realization of the operations of the people impersonating Police Officers slowly dawns on the criminals and then the Police. They then agree to work together to outwit the foreign impersonators. This leads to bungling attempts to capture the gang to great comic effect.
