The Masked Mariner's Plague

A transatlantic liner returns to harbor with a creeping sickness that turns passengers into raving shadows. As quarantine seals the ship, a masked avenger — a former naval surgeon who hides his face and past — boards under cover of night. He must battle fevered mobs, a hothouse of eerie laboratories, and a clandestine cult exploiting the contagion. With wireless newsreels stoking panic and a race to the ship's boiler-lit bow, the Masked Mariner fights to uncover whether the plague is nature...or malice made in a lab.
