Deathwatch.
Man that film makes no sense.
*Spoilers*
A group of WWI guys take over a german trench, but it's haunted and cursed and shit. They end up hating each other, and everyone dies except for this one kid, who eventually gets sucked into the ground, sees all his dead mates but then escapes. The German prisoner they took starts talking perfect english "You saved me. You were the only one who tried. That's why you are free". So the kid gets out the trench, and walks off into the fucking mist, no explaination of where he's going or anything. The German sits down, and another group of WWI guys come over the hill.
