I was watching BBC4's reruns of 60s sci fi series "The Prisoner," and the very first episode is called Arrival.
In case you don't know, the plot of the Prisoner is that this guy has resigned from the intelligence service/government, and they suspect he has defected. So they kidnap him and put him in this secluded village untill he decides he wants to tell them why he resigned (and also the stuff he knows is so valuable that they're probably just going to keep him there). Anyway, every episode he tries to escape, and gets chased by this this white ball controlled from a secret nerve centre. Sometimes they try and make him think he's escaped so he'll spill the beans etc...
