Oliver Groman, aging town boss of crime-ridden Ashton City, has a stroke and a change of heart.
A masked cabal, 4 evil men led by a mysterious 5th, runs the town and works against Justice Inc.
Moves and counter-moves: Benson is hounded by a corrupt policeman, Smitty is framed for a murder and is sprung by a disguised Benson, a carful of criminals goes over a cliff, Josh spies on a corrupt judge, Nellie and Rosabel are found out and must be rescued, etc.
Benson acts as a detective, solving the puzzle of the Devil's Horns, and as a grim, frightening, no-nonsense crimefighter.
A giant safe is found in Groman's house, filled with ill-gotten loot, sought by all.
