Lee Marvin and Toshiro Mifune are the only characters in this rather unique film.  Sworn World War II enemies, they find themselves marooned on a desert island together.  The story moves along, as the American and the Japanese gradually learn to mistrust one another less and less.  Even though neither can make himself fully understood to the other, they finally manage to construct a raft together and sail to a different island, formerly occupied by Japanese military, but now abandoned.
