1960: Major Allison takes his plane 100 miles above the Earth's surface for a test flight. Egads! He gets up to 500,000 mph, and as you can imagine, returns to Earth 65 years into the future. The airfield is in ruins and so is the neighboring city. He is captured by survivors and brought to their subterranean city. The leader, knows as The Supreme (Vladimir Sokoloff) and his right hand man, The Captain (Boyd "Red" Morgan) believe him a spy. Lucky for Allison, The Supreme's granddaughter, who has ESP and can read thoughts, takes an instant liking to him. This appears to be Allison's lucky day. Every man 65 years into the future is sterile and mute, and Princess Trirene needs a mate to help the human race propel into the future, The two get along famously, but danger lurks. Outside the gates, mutants desire to penetrate the subterranean city in order to eat the men and rape and eat the women. By the way, all the women are babes adorned in outfits right out of the "Star Trek" TV series.
However cheesy and sappy this film appears to be....don't be fooled. Eventually, the wondrous elements of the science fiction genre will give way to horror and a very dark conclusion. As mentioned above, when the mutants do get in, cannibalism and rape will be introduced into the plot. Trirene is stunning in her futuristic outfits, and also in a skinny dipping scene. Available on Netflix, take a look at "Beyond the Time Barrier."
