 In the highland forest, Captain Ryan (Liam Cunningham) and his Special Forces Unit, which includes Sergeant Walker, are spying on the squad of British Soldiers who have been set up as bait for a family of bloodthirsty werewolves. However, the werewolves attack the Special Forces Unit first. Ryan is badly injured and watches helplessly as his men are dragged screaming into the surrounding trees. Walker manages to escape the apparent slaughter, but unknown to him his unit s distress signal is picked up by a U.S. Command HQ on a nearby Isle. A small U.S. Unit, led by Sgt Martinez, are immediately sent in to discover what has happened to Ryan s Unit. They quickly find Ryan s demolished base camp and the apparent only survivor, Walker; but there are no signs of any dead bodies! What has happened to Ryan and the rest of his men? Now the Unit hear a distant gun-battle. Walker leads Martinez and her men on a race across the moonlit forest to rescue the original British Squad who are trapped in the remote farmhouse. However, a second pack of savage werewolves are in pursuit. The new pack is in fact the surviving members of Captain Ryan s SAS team now transformed into werewolves, but they have retained trace memories of their commando training. The new werewolves are faster, deadlier and smarter then the original Highland werewolves. These are true Dog Soldiers - and they are hungry for fresh meat.
