A team of coworkers for the UK division of a large defense corporation are brought to Hungary for a morale-boosting brainwashing session centered around teamwork. Before arriving, their bus is stopped in the countryside by logs blocking the road, leaving them to go the rest of the way on foot. But pothead Steve (Danny Dyer) thinks he sees people in the forest. Steve's right... soon after everyone manages to settle in (and get on each other's nerves), they are gruesomely (and comedically) taken out by disenfranchised soldiers, courtesy of the very weapons they created for the wars that drove them mad enough to kill.
