This episode of "The Prisoner" is special, very intense and disturbing. The whole serial is a masterpiece. It's precisely through the samples placed at the end of Death In June's "93 Dead Sunwheels" that I discovered about it. I must say thank you to Douglas P. also for this.
All of the episodes are available on youtube by the way, thanks to this uploader. And the other episodes seem to be in a much better quality than the first one posted here.
Thank you for turning me onto this show
