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.

Great, Charming, Profound

The King of Hearts should be seen by a new generation of viewers now in the summer of 2004. This is a great fable--which during the 1980s might have seemed dated, but now is more relevant than ever. It is a great meditation on war. As a movie, the circus-like atmosphere and characters combine to form a grand entertainment. We get seduced by the world of childlike imagination and sense of wonder we see in the inmates. We embrace them. Great

Great philosophical moments abound--all surrounded by beautiful colors, wonderfully funny moments and a gorgeous music score. The final scene is such a classic-- and takes the audience by such surprise--one goes out of the film absolutely exhilarated. A funny, charming and ultimately profound film.
