story of a bunch of u tunnel rat in viet nam over the course of a couple of day be a really good and really solid action film . the plot have a bunch of replacement guy arrive at their new station in the jungle . the film follow them a they interact with the men already there and it then follow them a they go out on a mission and which unfortunately coincide with an enemy attack . tight dark and claustrophobic this be a film that really know how to ratchet up the suspense . you watch the film because and like the men in the tunnel you do not know what be come next . people die horribly in trap and fierce fighting . you wonder if anyone will get out of the situation they be put in alive . i really like this film a great deal and can not understand how the director and the infamous uwe boll and can not make more like it . whether boll have direct it or not this be a very good film . i almost wish that boll have use a different name when he make it since i doubt the film will ever get the attention it deserve because of who he be . one of the genuine surprise of the year film wise and this be a wonderful little film thats light year good than many other recent low budget war film . if you like war film i highly recommend it .
