American film star Carlyle Blackwell stars in the British melodrama The Wrecker. Based on a play by Arnold Didley and Bernard Merivale, the story concerns the intensive search for the title character, a mysterious saboteur who gets his jollies out of wrecking trains. Hero Roger Doyle (Joseph Striker) and heroine Mary (Benita Hume) can't figure out how the Wrecker manages to be in so many places at once. Eventually they discover that the villain -- played, to no one's surprise, by Blackwell -- sends out recorded messages to his various minions, one of whom spills the beans. A climactic chase aboard a speeding train (a cliché, but an effective one) brings The Wrecker to a rousing conclusion.
