Synopsis
A soldier is expected to never question the actions of his commanding officer, but when a Marine sees his CO breaking the law, he finds himself facing a difficult dilemma in this provocative war drama. The trouble begins when the officer kills another soldier during a battle. The Marine who witnesses it wants to report it, but fears that the other superior officers will not believe him.

The Marine cryptically quips, "Nobody knows anybody...." ~ Sandra Brennan, All Movie Guide
