The Emperor of Japan has sent the U.S. President a very special Asian horse. Three incredible rogues hear of this horse and decide to kidnap it for a $500,000 ransom. One of them, the "white" is Giuliano Gemma, a grandiose kleptomaniac. Tomás Milian is the "yellow," a Japanese samurai, and the last ("black") is Eli Wallach, a goofy and gullible sheriff who has been victimized by "white" before, and will be again. The alliance between the three is a shaky thing, but "black" will have stumbled into clover.
