Here is a British horror film with a small budget reasonably spent, and a couple of interesting ideas, but let down by a very flat script. British feature newcomer Rob Green directs this wartime tale: it's 1944, and a German platoon in ragged retreat from the Allies takes cover in a bunker in the Ardennes forest. They are haunted by flashback-memories of an atrocity in which they participated, and a first world war veteran, holed up in the bunker with them, tells them that evil spirits are all about: "These woods are older than Germany itself!"

The stage is set for some ghosts in the bunker's deserted corridors, but their impact is lost in the muddled screenplay which never lets us know whether we should be scared of ghosts arising from their recent brutality or some ancient Blair Witch situation. Like the recent British chiller Lighthouse, it becomes claustrophobic for all the wrong reasons.
