Yet another story that imagines life after a third world war. Rod Serling speaks in his introduction as though this could be on another planet, or a near extinction of people that may have already happened. In any case it is concerned with the then topical subject of nuclear war and survival following it. A pretty similar scenario was to emerge in the fifth season as well (similar down to the respective ladies' eye shadow).
The deep-rooted mutual hatred of the enemy forces become obvious by the way the two principals regard each other with such suspicion years after the hostilities ended. Both Charles Bronson and Elizabeth Montgomery give their best to make this TZ an interesting one that takes you into a fascinating imagined future situation resulting from humanity's self-destructive nature. An effective entry because there's such a feeling of danger, even just between a man and a woman, and after an apocalypse. It suggests to me two cultures that have taken on an irrational level of mutual hatred. No doubt fuelled by vile propaganda on each side.
The 'Bewitched' contingent in TZ all made good episodes. Dick York in 'A Penny For Your Thoughts' and 'The Purple Testament'. Agnes Moorhead in 'The Invaders', and David White in 'A World of Difference'(plus the not good 'I Sing The Body Electric').
