The Lavender Hill Mob (1951)

Holland, a shy retiring man, dreams of being rich and living the good life. Faithfully, for 20 years, he has worked as a bank transfer agent for the delivery of gold bullion. One day he befriends Pendlebury, a maker of souvenirs. Holland remarks that, with Pendlebury's smelting equipment, one could forge the gold into harmless-looking toy Eiffel Towers and smuggle the gold from England into France. Soon after, the two plant a story to gain the services of professional criminals Lackery and Shorty. Together, the four plot their crime, leading to unexpected twists and turns.
