Travelling photographer Professor Jacoby (Sebastian Cabot) is treated like a celebrity during his visit to Dodge City, with the locals showing up in droves to have their pictures taken. What Marshal Matt Dillon (James Arness) doesn't realize (at least not at first) is that Jacoby is a ruthless self-promoter, determined to make himself nationally famous with his "wild west" pictures--even if it means provoking a gunfight in which an innocent man is killed. But the Professor gets his just desserts at the hands of some Indians who take violent offense at his photographic intrusions. This episode is based on the Gunsmoke radio broadcast of May 6, 1956. ~ Hal Erickson, Rovi
