Synopsis by Hal Erickson
A small community is terrorized by an unknown serial killer, one "Mr. Zero," who has held the populace in thrall for several weeks. The mysterious murderer takes refuge in the storage area of a department store, where Linda Allen (Mary Brian) works as a store detective. When jewelry-department manager Tommy Braddock (Russell Hardie) is suspected of being Mr. Zero, Linda endeavors to clear his name, and in so doing follows the trail of clues to the real killer. Inasmuch as Zero has already murdered a snoopy shoplifter, he has no qualms about putting his fingers 'round Linda's lovely throat..To give away the killer's identity would be unfair; suffice to say that the actor will be quite familiar to western and serial buffs.
