During World War I, a British private, sent ahead to a French town to scout for enemy presence, is mistaken for a King by the colorful patients of an insane asylum.
During the latter part of World War I, Private Charles Plumpick is chosen to go into the French town of Marville and disconnect a bomb that the German Army has planted. However, Charles is chased by some Germans, and finds himself holed up at the local insane asylum, where the inmates are convinced that he is the "King of Hearts". Feeling obligated to help the inmates, Charles attempts to lead them out of town, but they are afraid to leave, and frolic about the streets in gay costumes. — Rick Gregory An ornithologist, mistaken for an explosives expert, is sent alone into a small French town during World War I to investigate a garbled report from the resistance about a bomb which the departing Germans have set to blow up a weapons cache. He arrives to find a very eccentric group of townspeople, inmates of the local insane asylum, as it turns out, who have stepped into the characters of the fleeing villagers. — fyr
