Windtalkers (Blu-ray) (2002)

HIGH LEVEL VIOLENCE, ADULT THEMES

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.
