Gunsmoke is an American radio and television Western drama series created by director Norman MacDonnell and writer John Meston. The stories take place in and around Dodge City, Kansas, during the settlement of the American West. The central character is lawman Marshal Matt Dillon, played by William Conrad on radio and James Arness on television.

For thirty years, Marshall Matt Dillon fought to preserve the law in Dodge City… now, he's wanted for murder and fighting to clear his name. Three deputies ride up with a warrant for Dillon's arrest, a wealthy mine operator has been gunned down in cold blood and an eyewitness says Dillon was the murderer.

Retired marshal Matt Dillon tracks Arizona rustlers and lands in the middle of the 1880s Pleasant Valley War.
