An aging lawman in the turn-of-the century West finds himself out of step with the times and reluctantly accepts a job as a deputy to an inexperienced college-educated Police Chief in Oklahoma. He uses his brain and primitive beginnings of early-day criminal science to solve crimes.
The electric chair is about to make it's Western debut with a captured killer, but someone is attempting to cheat justice. Someone is making annonymous threats that there will be a murder a day until the killer is set free.
Hec sets out to clear innocent Indians and catch the real killers of three ranchers. Color blindness is a strange key to solving the mystery.
Hec acts as lawyer to a former girlfriend. Savannah is accused of killing the son of the richest man in New Mexico, a powerful man who controls both the Sheriff and Judge.
Hec hunts the killers of his fiancee, Norma Muldoon and her son Andy during a stagecoach robbery. His chief suspect is the son of an old friend and fellow lawman.
