Blackmail

Criminal Arnold Woodman (Herbert Vigran) and his two confederates plant 20,000 dollars in stolen money on Inspector Henderson (Robert Shayne), then threaten to accuse him of taking a bribe unless he does what they tell him. Playing for time, Henderson agrees to follow orders, which does not sit well with his reporter friend Clark Kent (George Reeves). Nor do things bode well for Kent's alter ego Superman, who has been targeted for extinction by Woodman through the deployment of a sure-fire doomsday weapon (well, it seemed like it was sure-fire on the drawing board, anyway!)
