Gunsmoke on CBS

Cameron Mitchell guest-stars as Chauncey Demon, a once highly respected sheriff who has let himself degenerate into a saloon bum, and whose old friend Matt Dillon won't accept his condition as final.

A series of seemingly random killings have the citizens of Dodge City in near panic, but Dillon believes they are part of a pattern in which Doc is slated to be the next target.

A sequence of tragedies leads to the death of three cowboys, one of them an old friend of Matt's.
