The military draft is back. Three best friends are drafted and given 30 days to report for duty. In that time they're forced to confront everything they believe about courage, duty, love, friendship and honor. If called to serve, what would you do?

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.
