Station 17 becomes Gotham’s last line of defense when a series of impossible fires begins targeting the city’s corrupt industrial infrastructure. As Captain Rowan Cade, Aaliyah Khan, Theo Briggs, Luis Ortega, and Detective Crispus Allen uncover the truth behind the arson attacks, they realize Garfield Lynns — Firefly — is not burning Gotham at random, but completing a buried tragedy the city chose to forget. Across the limited series, FIREFLY follows ordinary firefighters facing an extraordinary inferno, as old guilt, systemic corruption, Doctor Phosphorus, and Firefly’s final act of destruction collide in the ruins of the past.
