"Welcome to hell," are the eerily prophetic words, complete with shells, atmospheric all-is-not-right music and the groans of dying men, a hint of what's to come. After the battle, out of the fog and into a German trench, the men of Y-company discover that's exactly where they've landed. First of all, the place is deserted. And strewn with (mutilated) corpses of German soldiers. All dead. Except one (Torben Liebrecht), who warns them desperately that there is "quelque chose de mal" in that place, and to get out as soon as they can. Naturally, they all ignore him, except for Shakespeare (Jamie Bell). Soon, it proves true when the men start turning against each other, or getting sucked into the earth with barbed wire, or tying each other up à-la-crucifixion.
