Season 4, episode 4. Dennis Hopper plays a neo-Nazi trying to find his voice in this surprisingly compelling episode. Rod Serling wrote this episode, and he had a tendency to be very outspoken on certain subjects. Hopper gives a great performance, and this is perhaps the youngest I've ever seen him.

If only more people TODAY would watch shit like this, we wouldn't have so much political fuckery these days. Twilight Zone gives us some great morality tales.
