American answer to this was Nowhere Man (1995)

It aired on the disastrous UPN channel (started by Paramount as a competing TV network to cash in on their Star Trek franchise, and then promptly run into the grown by the station's highly incompetent heads) and just like almost every other show that premiered on UPN during their first year of broadcast - it got butchered in ratings and immediately canceled (this almost happened even to Star Trek: Voyager). Too bad, because Nowhere Man really was a legitimate US TV's answer to Prisoner. Sure, the lead wasn't a badass agent, but that was the point. And the paranoia, the atmosphere of total distrust and loneliness and unpredictability of the episode's (sometimes ludicrous) storylines definitely kept you invested and guessing. Even the ending was quite controversial, ambiguous and nonsensical, almost as much as the Prisoner's (although let's face it, nothing can top the Prisoner's ending, but Nowhere Man did try). To be fair, while it's true that this wasn't suppose to be Nowhere Man's series' ending - just season's, since there were no more episodes, it pretty much the same thing. If you love The Prisoner, you'll probably like Nowhere Man a lot. The only real difference (other than the type of the protagonist) is that in Nowhere Man the Island is in a way the US itself, pretty much.
