Matt (James Arness) has reason to believe that fugitive outlaw Jim Glass, former accomplice of Billy the Kid, is living in Tescosa under the name of Nate Timble. Investigating, Matt can't help but notice that the mild-mannered Trimble (Carl Betz) spends most of his time trying to rehabilitate a derelict cowboy. Just what exactly is Nate's game--assuming that it is a game? This episode is based on the Gunsmoke radio broadcast of August 22, 1953. ~ Hal Erickson, Rovi
