Windtalkers

WWII. Joe Enders, a decorated Marine who is by-the-book to a fault, is just coming back on duty (by cheating on his medical tests). "Ox" Anderson, much greener, is also getting the same new task: Protect the Navajo codetalkers (Ben Yahzee and Charles Whitehorse, respectively). While Enders is initially frustrated with his assignment, his respect grows as the codetalkers prove their worth in the brutal battle to take Saipan.

In the close quarters and brutal fighting of the World War II Pacific Theater, the U.S. Intelligence services desperately seek a fool-proof encryption code, immune to the code breakers of the Japanese. The answer is soon discovered in the ancient language of the Navajo. Enlisted into the Marine Corps are several "Windtalkers" who are deployed to frontline areas in the Pacific, to use their language as an impossible-to-crack secret code. A drawback, however, is that the U.S. military soon puts forth a directive that the Windtalkers must never be captured alive by the enemy, so additional Marines are assigned to make certian that this directive is carried out to the letter.
