Five builders are hired to work on a huge old farmhouse in the Welsh mountains, which are very far from the city. Housed in moldy portacabins, tensions quickly rise between the men and the self-entitled aristocratic homeowner, as well as among the group of men. Dave, a world-weary old man, and Bob, a kind Foreman, try to keep things calm. It turns out that his nephew Steve falls under the influence of bigot Jim. The two of them don't like Viktor, a Ukranian construction worker, so they don't like him. Tempers flare when the weather turns cold and bills aren't paid on time. Blood has been shed. As the blue-collar men face more and more difficult moral choices, Jim makes an incredible offer.
