A physicist (Julian Wadham) enlists a team of gruff interchangeable mercenaries only somewhat distinguishable by their accents to provide him safe passage to a bunker in the middle of an Eastern European country in the middle of a civil war. The trip to the bunker is uneventful but inside the dark corridors they find several bodies including one unresponsive survivor. They are soon under attack by unseen troops (shades of THE BUNKER). The medic of the team pulls a WWII-era bullet out of one of the injured mercenaries but discovers that it has never been fired. As the physicist checks out a bizarre machine, the others start to get gorily picked off by dark figures (kind of reminds me of SCARECROWS). They discover a WWII film depicting Nazi soldiers experimenting on enhancing their soldiers (shades of SHOCK WAVES) with the machine which is supposed to meld the corporeal forms of the soldiers with the elements around them rendering them invulnerable to bullets since they seem to exist in more than one dimension. Their only chance to escape is to lure the soldiers into the bunker so they can be contained by the machine.

SPOILERS: As with most of these films of solders/mercenaries/whatever encountering unseen and unstoppable forces in foggy labyrinthine forests and sheltering in old bunkers, no one survives and the next bunch of soldiers make the same discoveries and encounter the same apparitions.

While not perfect and pretty predictable, the film moves at a brisk pace and the gore is surprising (though still within the constraints of a relaxed R rating).

In keeping with some tiresome trends, the film has a colorless look that seems less cold than extremely muted. According to the imdb, the film was shot in anamorphic 35mm and the color correction done on a digital intermediate. The film's deleted scenes have saturated color (kind of like comparing the English and Italian prints of Argento's TRAUMA) and video like sharpness (the film itself has more a softer film-look to it). The deleted scenes are the only film-related extras on Sony's DVD (they are an option on the main menu instead of a bonus menu). There are several trailers on the disc (at startup or selectable from another menu) including the awful-looking APRIL FOOL'S DAY remake which seems to have nothing to do with the original and doesn't look nearly as clever.
