总统授权在偏远的大西洋西北进行一个住宅区发展计划。这是一个保护并且照料美国最有价值的脑力资源的地方。在那儿，我们国家最伟大的思想家，超级天才们致力于创造科学成就的新纪元，而他们的生活和工作会得到非常好的支持氛围。最好的建筑师和规划师们被委任为这些天才们设计一个受欢迎的地方定居。这个地方能为他们的孩子提供最好的教育，最好的医疗服务，最好的生活福利设施以及生活质量。这个社区的建设堪与美国最优美的田园风光小镇相媲美。只是它们之间有个重要的区别：这个小镇不会出现在任何地图上。至少无一不是被五角大楼划分于“只有眼睛”之类。 就这样尤利卡小镇诞生了。但是对于所有熟知小镇的人来说。小镇拥有一切，但没有秩序。老派而健忘的教授因为某种原因而存在于小镇上；在过去五十年间，大多数科技上的突飞猛进都是尤利卡镇的精英研究者们取得的。然而不幸的是，科学的探索总是出乎人们的意料。经年的试验走了歪路，产生了怪异的副产品。
