Two American soldiers in Iraq, pinned down in the desert by an unseen expert Iraqi sniper, are the focus of the film (and the only characters you will see for 99% of the time), with only the eponymous (crumbling and small) wall protecting them from certain death. If this sounds intriguing to you, you may find this 80-minute psychological flick entertaining, if a bit slow, although the ending is not where I thought the story was leading the audience.
