The niece of Ray Endicott, one of the soldiers from Joe Mannix' old unit in Korea, is murdered in her apartment, and a lighter found there links the killing to another member of the unit, Tommy Gantt, who once dated the girl. But Mannix isn't convinced of Gantt's guilt, and begins to believe that the real killer is yet another former member of the unit -- who may be taking revenge on his former comrades one by one.
