Dennis Hopper stars in this episode, as a second-rate Neo-Nazi who’s trying to bring his fascist movement to fruition in the US. He’s being guided by a shadowy figure, who turns out to be Adolf Hitler, who eventually convinces Hopper’s character to kill.

In his closing monologue, Rod Serling warns that while HItler may be dead, his ideas and the intolerance and cruelty he stood for, haven’t gone away. Bigotry, racism and white supremacy still exist in the world, despite the fact that we know better.
