Their U-boat having been blown out of the water by the Canadian air force, six German survivors find themselves on a desolate peninsular of Northern Canada, their only hope, to hijack the Allied plane that has been sent to capture them. This Second World War propaganda film by Michael Powell, intended to encourage a still isolationist America into battle, has to be one of the most intelligent and thoughtful films of its kind, an attempt to understand hearts and minds, regardless of their side, rather than a simplistic jingoism built on fear.
