Wall of Crystal

Newly married Bill and his new bride lose control of the car. They run a truck off the road, and its driver staggers from the vehicle, falls, glows red and vanishes! Then the young couple suffocates. It's all part of a scheme run by the alien Taugus, and it draws in David's brother Bob, Bob's wife Grace, and crusading newsman Theodore Booth. David's finally managed to convince his brother and someone able to get the word out that he may be telling the truth about the aliens - but is it just in time to see the entire human population choking for air on their own planet?
