There were a few of these wartime dramas designed to bring attention to the atrocities being carried out by the Nazis on the erstwhile peaceful people of Norway. This one finds "Eric" (Paul Muni) flee to Britain where he trains and returns to his homeland determined to wreak revenge on his occupiers and their Quisling allies and to help the British to successfully bomb an airbase being built at altitude that could be used to attack allied territory and shipping. It's all a bit meandering, however. Muni isn't really a very convincing Norwegian nor is Alexander Knox particularly menacing as a captain in the Wehrmacht nor Rod Cameron as the Pastor. Indeed, aside from Sir Cedric Hardwicke as the archetypal British admiral, none of the casting works especially well here - and coupled with some very wordy dialogue, that manages to drag this down a little into melodrama territory. It ends rousingly enough, though, and given it's purpose was largely propagandist - it does what is says on the tin. Watchable, but forgettable fayre.
