Bruce Reynolds was a career criminal who - looking for his defining moment - started planning a daring train train robbery over a period of three months in 1963. Reynolds secretly organised a gang of 15 men to bring down a Royal Mail train carrying over two million pounds in cash. Amongst London’s underworld this was called the ‘holy grail’ of robberies but no one had ever attempted it because it was too hard and dangerous. No one until Reynolds that is. Quickly dubbed the Great Train Robbery by the press, at the time it was Britain's largest robbery. While most of Reynolds gang was caught by the renowned Tommy Butler of Scotland Yard, Reynolds spent five years on the run before Butler finally nabbed him.
