Watch Fmovies. At a mine on the shared edge of France and Germany, an underground explosion leads to the entrapment of a group of French miners. In an effort to save the trapped Frenchmen, German miners Wittkopp and Kasper take it upon themselves to traverse a crumbling war tunnel leading down into the mines. Yet, though the workers harbor no political biases against one another, their callous, less tolerant bosses hope to halt this cross-cultural rescue mission.
