Thrilling drama of the new secret front!

When Hitler invades Poland, sports journalist Colin Metcalfe (Hugh Williams) is unexpectedly reassigned as a foreign correspondent in Norway. En route, his ship is attacked by a German U-boat, but his warning to the Royal Navy is dismissed and he loses his post. With the German invasion of Norway soon after, Metcalfe returns, determined to uncover enemy operations and strike back against the occupiers. (Note: The film was released in the United States under the alternate title The Avengers (1942).)
