The Innocent
David Vincent is contacted by Captain Ross, US Air Force. Ross has first hand knowledge of the Invaders and wants Vincent to testify about what he has seen in front of the Peterson Committee of the US Congress. Vincent is in Maine trying to track down Nat Greeley who has one of the Invaders weapons, a disc. The Invaders are also looking for Greeley.
The Invaders get to Greeley. They capture his kid. He helps them to capture David Vincent. Magnus, the leader of the Invaders, makes an effort to convince Vincent that his people don't want to do the people of Earth any harm. He takes him on a trip in a space ship. The go to Santa Margaretta, a town where David used to live. He reconnects with Billy Stearns, an childhood friend, and Helen, an ex-girlfriend who wants to get back together with him. It all seems so good but Vincent senses that something is wrong.
It turns out that the whole trip is an illusion. They never went anywhere. Magnus just made him think they did using a high tech device. David tries to escape. Magnus wants him to call Captain Ross and tell him that he was mistaken, that he has nothing to tell the Peterson Committee. David refuses until they threaten to kill Nat Greely's family.
Vincent makes the phone call. The Invaders won't let him or Greely go. The Invaders force them to drink whiskey and then put them in a car which they send hurtling down a mountain road. The brakes don't work. The two men barely survive the experience.
Thoughts
This was a pretty good episode although its funny how the Invaders keep changing their approach to David Vincent. In the earliest episodes they just wanted to kill him. They attempt to convince him that they are only trying to help the Earth in this episode but when that doesn't work they resort to their old ways.
