Dog Soldiers opens in the misty mountains of Scotland. A couple of working stiffs (one of whom seems to be a writer) are celebrating something. The girl stiff (played by Tina Landini) hands her knight a letter opener made out of pure silver. The male stiff (Craig Conway) is left speechless. As with most camping couples, this ugly pair of John Bulls are rather randy and soon start making boom-boom. In a brilliant shot, as the man slowly zips down his lady's trousers, he realizes that someone is zipping down the door to their tent. It's a werewolf, not a prowling peeper. Enter lots of blood, howling, and an exquisite shot of a full moon.
Anyway, back to the movie. After failing, Cooper is RTU'd (returned to unit) just in time for an exercise pitting the regular British Army against the SAS. The exercise takes place in the Highlands--the very same Highlands where campers have been going missing at an alarming rate. According to Cooper, the team's lone Scotsman, the papers blame the killings on a terrific beast, something like the legendary Beast of Bodmin Moor. Others point to an escaped lunatic that's gone blood hungry. We, the audience, know that the culprits are the offspring of Lawrence Talbot.
The team's first KIA is Corporal Bruce Campbell (played by Thomas Lockyer). The unlucky bastard runs into a super sharp tree branch before being gutted by a lycanthrope. Next on the chopping block is Sergeant Wells himself, who suffers a torn gut that spews out extra red and raw sausages. The team only manages to drag him and themselves to safety thanks to the timely intervention of a civilian (played by Emma Cleansby). Megan piles the men into her yellow Land Rover and finds shelter in a very isolated farmhouse. There are no phones inside the house, plus the nearest town is four hours away. The only plus sides are the dog and the food that the house's missing family left behind.
The film's penultimate betrayal comes when Megan reveals that she has led the men into their last trap. She's not only a wolfie, but she's also a member of the family that has been trying to kill Private Cooper and company since the twenty minute mark. This leads to a gigantic blowup involving the few remaining men and the whole pack, including Captain Ryan. A stove leaking gas gets involved, and I hope you didn't forget about that silver penknife, for it too plays a part. Only one man survives the whole ordeal. I'm sure you can figure it out.
