Operation Snatch plot
"For the first time the Rock really rocks with inspired lunacy."
Legend has it that if the monkeys leave the rock of Gibraltar, the British will lose out. That's why a British officer is stationed in Gibraltar during World War II to keep the monkeys under control. When he notices that the monkeys' morale is falling, he devises a plan to kidnap a monkey behind German lines to raise the morale of the other monkeys. That has to happen before the Germans find out that the monkeys on Gibraltar are in bad shape and can use that as propaganda.
