When nine National Guardsmen enter the Louisiana swamp for routine training, they are unaware that just a handful of their ranks will make it out alive. Through an error in judgment, they incite an all-out war with some angry Cajuns who know the territory like the backs of their hands. Armed with a precious few bullets, and confused by the dimly lit, moss-covered maze into which they've stumbled, the innocent guardsmen know they'll be picked off one by one, until they come up with a solution using the only resources they have left themselves.
