Paris, 1793. During the bloodiest days of the Reign of Terror, a brilliant but reclusive clockmaker named Henri is drawn into a deadly game of espionage when a disguised aristocratic woman brings him a broken pocket watch. Hidden within its gears is a cipher containing the route to safety for her condemned family. As the ruthless Committee of Public Safety closes in, Henri must use his mechanical genius to forge government documents and engineer a daring escape through the labyrinthine catacombs of Paris before the guillotine claims them both at dawn.
