Colton, a Union Army Captain, spends the years following the Civil War wandering from town to town in the American West, meeting old friends and strangers alike and helping them solve their problems while trying to find himself.
The show followed the basic format of other Western shows such as Have Gun Will Travel and Maverick, but added Serling's trademark philosophical qualities in an attempt to make a Western series for mature audiences. CBS wasn't happy with show's focus on ideas over action, however, and when ratings failed to elevate the show's status it ended up being cancelled at the end of its first season.
The show's theme music was composed by Jerry Goldsmith (he also scored "An Echo of Bugles" (the first episode) and and "One of the Wounded".
