You can give up killing, but death never leaves you ...

After a lifetime of hunting down criminals, Ryan just wants to live out his days in peace and in the shadows of Tokyo to grieve the loss of his wife and son. But his old team—the Nameless, experts in extraction and recon—comes with an urgent request for help. The young daughter of one of his closest friends, a girl he once treated as his own, has been kidnapped.

The search leads Ryan and his team into the Japanese mountains and a town steeped in secrets that a new sinister adversary wishes to keep hidden. He begins to unravel a deep, macabre plot that goes far beyond this missing girl. With enemies from the past reemerging, they begin targeting members of the Nameless. Ryan quickly realizes that no matter how hard he tries to leave this world behind, it will never let him go until he defeats his demons. Those demons are not just after him, and if they aren't stopped, it could put all of humanity at risk.
