Filmed in Japan, Sam Fuller's 1955 crime noir tells the story of Eddie Kenner (Robert Stack), a U.S. army operative sent to Tokyo as an investigator. A gang of American expatriates is robbing U.S. military ammunition and supply trains, and using military tactics to do it. They're a ruthless bunch, killing not only any troops and police that get in the way but also their own wounded. Working undercover, Kenner must gain the trust of ex-soldier Sandy Dawson (Robert Ryan), who now heads the gang. The beautiful Japanese wife of a slain gangster is all too willing to help.
