From a technical standpoint, this episode of "Tales of Tomorrow" isn't great. Especially in the opening sequence, there are plenty of flubbed lines--so many that I assumed it was filmed live or the show was so sloppily done that they ignored the mistakes and aired it anyway.
The show is about the work of Mr. Calhoun--a government investigator who is trying to get the bottom of some espionage happening in a plant in California. However, using a fantastic new lie detecting device, he learns nothing--nothing other than somehow people are now able to cheat the system.
There are two main problems with this episode. First, the surprise twist isn't all that interesting nor strange. I actually saw it coming. Second, the show never really did resolve the espionage problem--and they forgot about it completely! All in all, one of the weaker episodes of an otherwise interesting anthology series.
