Following a failed mission Off-World, the only two survivors of a combat squad, ex-marine Mead and Replicant combat model Stix, have returned to Tokyo to search for the traitor who left them to die. Now operating as an unofficial private detective agency, Stix and Mead find themselves caught up in a deadly Patent War between the Yakuza, the Tyrell Corporation and Cheshire, a rival corporation developing their own bootleg Replicant technology as they search for a missing woman.
