Southern Comfort (Blu-ray)(1981)

Nine National Guardsmen enter the Louisiana swamp for routine training, but an error in judgment by one of the team incites 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 guardsmen know they'll be picked off one by one, until they come up with a solution using the only resources they have left - their wits. Also starring Fred Ward (TREMORS, 2 Guns), T.K. Carter (THE THING), Peter Coyote (JAGGED EDGE) and Brion James (BLADE RUNNER).
