It's become the fastest—and surest—way to get from here to eternity. Somebody is playing the railroads like a giant train set, causing high-speed derailments that strew the rails with headless victims from coast to coast. And could the repeated sightings of a ghostly samurai swordsman be fact or mass hysteria?

 

As the carnage continues unchecked and the body count mounts, Dr. Harold Smith suspects the train terror is merely a decoy for the real target. He sends Remo Williams and Master Chiun to ride the rails, posing as investigators for the Department of Transportation—clearly an equal-opportunity employer who won't discriminate against aging Asians. And now Chiun and Remo get equal opportunity to literally lose their heads over an old enemy.
