Synopsis by Hans J. Wollstein
Chapter eight of Officer 444 reveals that rather than having been shot, "444" (Ben Wilson) had made the old "switcheroo" and the injured is instead the mysterious "Professor Kalium." In his continuing efforts to rescue Frank Haverly and save Haverlyite for mankind, "444" briefly masquerades as chauffeur to the evil mastermind The Frog and witnesses the spectacle of The Frog boarding the automobile as himself only to disembark as "Professor Kalium." Following a tip, everyone convenes at the Dragon Café but Professor Kalium and The Vulture are already heading toward the border with their captive, young Frank Haverly (Phil Ford). In hot pursuit, the police van carrying "444", Gloria, Officer Casey (Jack Mower) and Snoopy the newspaperman (Harry McDonald) careens off Dead Man's Grade and into a ravine.
