Several thousand years from now, advanced humanoids known as the Makers will implant clockwork devices into our heads. At the cost of a certain amount of agency, these devices will permit us to move unhindered through time and space, and to live complacent, well-regulated lives. However, when one of these devices goes awry, a “clockwork man” appears accidentally in the 1920s, at a cricket match in a small English village. Comical yet mind-blowing hijinks ensue.

The novel opens with the farcical setup of the Clockwork Man's abrupt appearance at an early-twentieth-century afternoon cricket match in the countryside, which he ultimately joins and wrecks. The novel soon changes tone, however, and views the threat and promise of the Clockwork Man from several perspectives, including that of a middle-aged doctor who has grown settled in his opinions and middling life and shame at his own lack of originality, and a young man who strains against convention and the predicament of his youth.

Along the way, the story challenges modern assumptions about efficiency, the tyranny of fast-paced life (and small-town opinion), and the value of free will.
