It is 14 years into the future, 1965. A perfect lie detector has been developed and accepted by the law community. There is, apparently, a one in one hundred thousand chance the thing will make a mistake. Some breech of security has taken place involving a guided missile project. A man is hired to question over 500 plant employees. They are all asked three questions: What is your name? What do you do? and Have you ever been in this room before. They are all cleared. One day, they suspect their phone is being bugged because of a clicking sound and they set up an audio trap to catch the bad guy. While trying to break into a safe, supposedly containing secrets, a man has his picture taken. They bring him in and soon the thing gets about as stupid as can be. Apparently, it doesn't matter if you murder someone in broad daylight in front of witnesses. If the machine says you didn't do it, you didn't do it. This thing is so full of holes, it could be mistaken for a woolen mill filled with moths. The conclusion is beyond belief.
