Summary
When Hank Morgan, a skilled and practical-minded engineer from 19th-century Connecticut, receives a blow to the head, he mysteriously wakes up in medieval England—specifically, the court of King Arthur. Armed only with his knowledge of modern science and technology, Hank is quickly deemed a sorcerer and narrowly escapes execution by demonstrating his “magical” ability to predict a solar eclipse.
Seeing opportunity in his predicament, Hank uses his knowledge to modernize Camelot—introducing schools, newspapers, gunpowder, factories, bicycles, and telegraphs, all under the guise of wizardry.
He soon becomes the "Boss" of the kingdom, clashing with the Church, the nobility, and the romantic ideals of chivalry.
But as his reforms grow in scale and his ego inflates, the tension between modern rationalism and medieval traditions comes to a dramatic and tragic head, leading to a climactic battle between Hank’s technologically armed force and the remaining knights of Arthur's England.
