Talented B-picture director Joseph H. Lewis wasn't yet in the "auteur" class when he helmed the PRC quickie Criminals Within. Eternal juvenile Eric Linden plays Greg, an Army draftee accused of stealing a top-secret document. Escaping from the stockade, Greg tries to clear himself by exposing the real criminal, who turns out to be a foreign spy. He is aided in this endeavor by intrepid girl reporter Linda, played by the talented Ann Doran in one of her few feature-film starring assignments. The "gimmick" in Criminals Within is a dangerous new explosive formula-and this was four years before Hiroshima!
