Captain Kentaro Washio takes Ken the Eagle on a blistering training run, but then gets a tip that Galactor is building a weaponized “attack city” designed to lure Gatchaman in and kill them all. With Doctor Nambu unaware and no time for backup, Kentaro goes in alone…and crashes straight into Berg Katse’s trap, where even the “citizens” are killer machines. Outnumbered, grounded, and fighting with nothing but grit and a sidearm, the Captain must demolish an entire city to keep his team safe…especially the son who doesn’t know their bond.
