This had more big name guest stars at the time than you can shake a stick at. So much interesting stuff happened in this one. For one thing, it began in Chicago with beautiful location shots and great examples of the Windy City! Also new and different is that the beginning credits that play over the first act included the guest stars in alphabetical order. That was a first. This is also an episode that paid such minute attention to detail that you just plain old do not get today. We get a closeup of Jennifer's California driver's license where we learn that she lives at 3100 Willow Pond; Hair, Auburn; Eyes, Brown; Height, 5'6"; Weight, 115; Birthdate is 11-2-46 (which is, incidentally, Stefanie's birthday), making her 34 years old at the time it was issued in 1980. FASCINATING. Filmed today, a thumb would simply be placed over all that important information. The stunt and location shots for this must have cost a ridiculous amount of money. These were real Amtrak trains, they were really moving for some of these spectacular stunts, and given the star power in this episode commanding some kind of big salary at the time, the $$ spent on this one ep alone must have been exorbitant. Money well-spent! The guest stars just never seemed to end. Florence Henderson, Ron Glass, David Doyle, Bernie Koppel, the consistently unfunny (sorry) Skip Stevenson (but with lots of funny in-joke lines written about his character being so unfunny), a very young and pretty Carol Linley ... it just didn't end. Most impressive? RJ's ability to get out the line, "For the last couple of days, while you've been gambling, a dead man in a wheelchair turned out to be protecting a government witness from a hired killer who tried to kill me!" And he looked genuinely relieved to have gotten the line out. I'm dying to know how many takes it was! It didn't take a genius to figure out who the bad guys were, but it did take me a while to get there. Well-written, well-directed, well-acted, the kicker was awesome; great episode! Seriously, there's no way this wasn't a sweeps episode.
