Homicide detective Sean Nault, a cop on a parallel Earth whose technology is powered exclusively by magic. Sean investigates a baffling series of murders committed by a means he's never seen before: science. With the aid of Lenoir, a member of the ridiculed subculture of "pragmatists" who believe science is more than the stuff of myths & children's stories, and the 130-year-old sorcerer Winston Churchill, Sean uncovers an ominous plot that will lead him to another dimension and the realization that, unless he prevents it, both earths could well be destroyed. 一般吧。 尚恩在另一个对比的地球担任重案刑警，不同的是那里的科技全都倚靠魔法运作。一次他着手调查一连串怪异谋杀案，犯案手法都是他过去从来未见，因为凭借是科学。他在雷诺，一名崇尚科学更甚于传说和童话的「实用主义」忠实成员，以及130岁的魔法师丘吉尔这两人的协助下，发现层层迂回的内幕，引领他来到另一个时空，也就是我们存在的地球。这时他才发现，如果他不出手阻止，两个地球都会面临毁灭。
