Synopsis
Agent James West goes to see Warden Primwick,who releases condemned murderer Ralph Kleed in his presence. Kleed blows a whistle,and the warden attacks West with his cane. West restrains the warden,who dies from the exertion. Kleed escapes,leaving behind a whistle that has a special pitch,apparently only heard by dogs and wardens. Through the warden's autopsy,agent Artemus Gordon discovers that a franconium crytal has been implanted in the warden's brain,prompting violent behavior when Kleed blew his whistle. West falls into the hands of master criminal Titus Trask,who intends to implant a crystal in the agent's brain and,in turn,have West do the same to President Grant so Trask can rule the country.
