This is one of my all-time favorite episodes, with strong performances (especially by Mason Adams) and a great plot. It was interesting to see the way they took the old Chinaman button concept and applied it to a real-world setting. The new version of the "The Twilight Zone" that came out in the 80's had an episode where a couple recieved a box with an actual button and were offered a million dollars if they would push it (resulting in the death of someone they would never know or meet). I'm glad CBSRMT choose to take a more metaphorical route.
The ending of this episode is particularly satisfying. On reflection, we should have see it coming. Van Hoss was so pious, so seemingly beyond reproach...yet willing to stab others in the back to maintain those high standards. He was a moral accident waiting to happen.
