An engrossing suspenser with dashes of comedy, League of Gentlemen is about a daring group of highly trained army men, turned bank robbers. When Hyde (Jack Hawkins) is drummed out of the army after years of devoted service, he decides to get back at society in general. One by one, he finds seven other army officers who are now broke and who walk on the shady side of the law. All eight men go into hiding as they plan the robbery with the care and attention of a behind-the-lines reconnaissance mission. As they undertake tasks like raiding a military depot for explosives and similar stunts, suspense and incidental humor increase, leading up to bank day when the really big show has to be pulled off without a hitch.
