The terrorists are planning to bomb a passenger train and Wynn Garrett is planning to stop them. But the typical non-specific threat means no one is sure when or where the terrorists will strike. To prevent the attack Wynn will need to be a passenger on the train - and he doesn't like trains! Wardahl and Scorby worry his usual behavior will incite panic among the passengers before he actually gets the job done. All is well that ends well, but with Wynn they're never sure how things will end!
