Dog Soldiers

A band of soldiers is dispatched to war games deep in the woods. When they stumble across a rival team slaughtered in camp, they realize they're not alone. Something deadly waits in the darkness; something not animal and not human. Holed up in an abandoned farmhouse, the soldiers start a bloody battle against the beasts. Dawn is only a few hours away, but they may not live to see it. (official distributor synopsis)
