The book's protagonist is an English scientist and gentleman inventor living in Richmond, Surrey, in Victorian England, and identified by a narrator simply as the Time Traveller. The narrator recounts the Traveller's lecture to his weekly dinner guests that time is simply a fourth dimension and his demonstration of a tabletop model machine for travelling through it. He reveals that he has built a machine capable of carrying a person through time, and returns at dinner the following week to recount a remarkable tale, becoming the new narrator.
