Apocalyptic saucer cults have started to spring up all over America. One small group, which has been receiving messages from outer space via Lake City housewife Mrs. Marian Keech, becomes the subject of a research team led by psychologist Leon Festinger. According to an alien entity named Sananda, the end of the world is due any day and under the most cataclysmic of circumstances. The group meets regularly to discuss the latest predictions from Sananda and the rest of the Space Brothers, all relayed to them by Mrs. Keech. Some members bake cakes in the shape of flying saucers to be consumed during their gatherings while local college football scores are closely debated.
