In a city fueled by secrets and decaying machinery, Arthur Vance, a reclusive clock repairman, is drawn into a high-stakes conspiracy when a woman named Clara brings him a broken mechanical bird.
Hidden within the bird’s gears is a century-old secret: a lens schematic and a coded song that reveal a ledger of systemic corruption etched into the very stones of the city's clock tower. Hunted by the powerful families who profit from these lies, Arthur and Clara must use ancient engineering to outsmart modern surveillance. From the depths of a coastal shipyard to a remote mountain peaks, they race to transmit the truth through the earth's crust, proving that even the most forgotten gears can change the world.
