For centuries, time has been controlled by clock towers, but when a tower is broken, time upsets. When a tower is destroyed, time Stops. Clock mechanics are tasked with fixing broken towers, but Stopped cities are unable to be rescued. In Victorian England, Danny Hart, a 17-year-old prodigy mechanic with a traumatic past, fixes clock towers that are victims of mysterious bombings across England while trying to find a way to save his father from a Stopped town. But in the process, he meets someone that most people believe doesn’t even exist: a clock spirit, whose name is Colton.
